Zelenskyy and Britain: three speeches to Parliament, six prime ministers and a treaty that runs for a century

The Ukrainian president has outlasted a whole cycle of Westminster politics. What has stayed constant is the room he keeps coming back to.

At about five in the afternoon on 8 March 2022, a screen was wheeled into the Commons chamber and parked near the Speaker’s chair, and MPs put on translation headsets, which is not a thing that happens in that room. Two weeks into the full-scale invasion, a foreign head of state appeared on it and spoke to the House by video link, the first time the chamber had been used that way. If you had been in the public gallery that afternoon, the odd detail would not have been the speech, it would have been the headsets: Westminster changing its own furniture for a man most of the country had first seen in a comedy series.

Four years later he has done it twice more, in person in 2023 and again in March 2026, and along the way he has worked through six British prime ministers. The offices change hands. The chamber does not.

Three, and each one was a different kind of event. The March 2022 address was remote and emergency-shaped, delivered from a bunkered Kyiv into a chamber that had never taken a live foreign leader on screen before. The February 2023 address was physical, in Westminster Hall, with the full apparatus of a state visit around it. The March 2026 address came at a point when support in London had become routine enough to need re-arguing rather than re-announcing.

That progression matters more than any individual line in any of the speeches. A wartime leader who gets one emergency hearing is a news story. One who gets three, spread across four years and three different governments, has become part of the furniture of UK foreign policy, which is a much harder thing to reverse and a much duller thing to report.

The Ukrainian side has been deliberate about it. Parliamentary appearances are cheap in diplomatic terms, they do not require anything to be signed, and they leave a record in Hansard that outlives whoever is in Downing Street that month.

Set the three dates against the list of people who have held that street address and the strategy becomes legible. Two of the milestones landed on Boris Johnson’s watch, one on Rishi Sunak’s, one on Sir Keir Starmer’s and one on Andy Burnham’s, and in every case the room in Westminster was the constant while the host changed. Kyiv has never had to rebuild the relationship from scratch, because the relationship was never stored in one person.

On 8 February 2023 an RAF C-17 brought him into Stansted, and the day that followed was built like a campaign schedule rather than a diplomatic one. Westminster Hall in the morning, where he handed the Speaker, Sir Lindsay Hoyle, a fighter pilot’s helmet signed with a line about wings, an object chosen because it made a specific request impossible to talk around. Then an audience with King Charles III. Then the training ground at Lulworth in Dorset, where Ukrainian crews were learning Challenger tanks, and where the pictures were of soldiers rather than officials.

Each stop was aimed at a different audience in Britain. The Hall was for MPs and peers, the palace was for the broadcast bulletins, and Dorset was for the part of the public that does not follow foreign policy but does recognise a tank and a recruit. The helmet was the only piece of the day anyone still quotes, and it was the cheapest item on the schedule.

British governments tend to prefer announcements to gestures. The visit worked because it supplied both on the same day, and because the gesture arrived first.

It was signed in Kyiv on 16 January 2025, by the Ukrainian president and Sir Keir Starmer, and its headline is its length. A hundred years is not a normal unit for a bilateral agreement, and that is the point of choosing it: the number is a message to Moscow and to future cabinets in London at the same time, and it costs nothing to write down.

Underneath the headline the document does ordinary treaty things. It sets out co-operation on defence, on maritime security in the Black Sea, on energy, on science, on grain trade and on rebuilding. It creates the frame that later, smaller agreements hang from, which is why Ukrainian officials kept referring back to it through 2025 and 2026 whenever a specific programme needed a legal parent.

The clause that does not appear in the press releases is the exit. Either side can leave with six months’ notice.

By the end of 2025 the UK total stood at roughly £21.8bn, of which about £13bn was military, with the rest running through humanitarian and economic channels. On top of that sits a standing pledge of £3bn a year in military support out to 2030 and 2031, which is the line that turns a series of emergency decisions into something closer to a budget item.

The equipment that made the most noise in Britain was Storm Shadow, the long-range cruise missile, because it was the first system where London moved ahead of larger allies rather than behind them. Challenger tanks came earlier, in smaller numbers, and mattered mainly as permission for other capitals to follow. Training has been the least glamorous and probably the most consequential strand, with tens of thousands of Ukrainian recruits put through UK ranges.

Stack the committed money against the promised money and the shape changes again. The £21.8bn already spent splits roughly sixty-forty between military and everything else, while the forward pledge is military only, so the further out you look the more the relationship becomes a defence arrangement with a humanitarian history. On the stated annual figure the whole thing tops out somewhere near £36.8bn, though that last number is arithmetic rather than a signature.

If you pay tax in the UK, this is the part of the relationship that is actually yours, and it is the part that gets re-decided in every spending round while the treaty sits quietly in a drawer.

Depends which question the pollster asks, and the gap between the two questions is the most interesting thing in Ukrainian politics right now. On the electoral question, who would you vote for in a first round, he was still ahead through 2026, with published figures ranging from the low twenties to the mid thirties depending on the sample and the wording. On the trust question, who do you trust most, he has not been automatically first for some time.

The names crowding in behind him come from outside conventional politics. A former commander-in-chief now serving as an ambassador, an intelligence chief, a thirty-five-year-old ex-digital minister. None of them run a party, none of them campaign, and several of them have said nothing about standing for anything.

Put trust and voting intention side by side and the interesting thing is not who leads either column, it is how little of the first survives into the second. The ambassador in London is trusted by roughly three Ukrainians in four and would draw around seventeen per cent as a party. The intelligence chief runs at similar trust and lands under thirteen. Admiration and a ballot paper turn out to be different instruments, and the incumbent is the one figure who inverts the pattern, polling lower on trust and higher on the vote.

You can read those numbers two ways. Either the incumbent is weakening, or the country is doing what democracies do when a vote is impossible: rehearsing.

Nobody has voted on any of this. Ukraine has not held a national election since the invasion began, and the legal position under martial law is that it cannot, which turns every one of these figures into a hypothetical. Coverage in Britain often skips that sentence, and it is the sentence that makes the rest of the numbers readable.

Four people in practice, and between them they cover five different parts of the machine. Valerii Zaluzhnyi, the former commander-in-chief, has been ambassador since July 2024 and sits at the embassy on Holland Park in W11, which gives Kyiv a permanent voice in London with a military reputation attached. Andrii Sybiha, foreign minister since September 2024, is the working counterpart for the Foreign, Commonwealth and Development Office. Ruslan Stefanchuk, speaker of the Verkhovna Rada, handles the parliamentary channel, and in October 2025 he became the first foreign parliamentary speaker to address British legislators in that particular format.

The president is the fourth carrier, and the only one who goes straight to the chamber without passing through any of the others, which is why his lines cross the diplomatic ones rather than running beside them. The ambassador is the only carrier who reaches industry, because a former commander-in-chief walking a factory floor in Belfast does something a diplomat cannot.

The division of labour is unusual for a country of Ukraine’s size. Most states route everything through an embassy and let the foreign ministry handle capitals. Kyiv runs four parallel lines because decisions here are taken in several buildings at once, and because a message that arrives only through government dies when the government changes.

Read down that final column and the pattern is plain. The early rows produced attention, the later ones produced paperwork, and paperwork is what a relationship looks like once it stops being an emergency.

Three things worth keeping an eye on, and none of them will be announced from a podium. The first is whether the £3bn annual line survives contact with a British spending review, because that is the number that turns into ammunition. The second is the parliamentary track, including the Crimea Platform summit that British legislators were preparing to host, since that channel runs on invitations rather than budgets and is therefore harder to cut.

The third is personnel. Kyiv’s most effective London asset is an ambassador who tops trust polls at home, which is a situation with no obvious precedent and no guarantee of lasting. If that changes, the shape of the relationship changes with it, whatever the treaty says.

Go back to the screen by the Speaker’s chair. It has been rolled in three times now, for three different British governments, and the thing that made March 2022 remarkable was that nobody had done it before. By March 2026 it was a scheduling question. That is what winning a long argument looks like, and it is also why the six-month clause is the line worth remembering: the century is on paper, the relationship is renewed every year, in a room where the furniture stays put and the ministers do not.
