Kemi Badenoch's first question to Starmer focuses on Ukraine, saying divisions between it and the US only serve Russian President Vladimir Putin.

Zelensky is right to try and rebuild his relationship with Trump, he's keeping a "cool head under very difficult circumstances", she says.

She asks the PM what he is doing to help rebuild their relationship after a challenging week.

A notable start to PMQs after US Vice-President JD Vance was apparently dismissive of the military sacrifices of allies in an interview with Fox News earlier this week.

The prime minister notably lists some of those lost in conflict, in the week their families are marking the anniversary of their deaths.

There are clear political sensitivities in where the cuts to welfare spending are likely to fall. The Labour Party has many factions and ideological nuances but all of its MPs are committed to a generous welfare state and many will be antsy at the prospect of welfare cuts.

Those in government are adamant, though, that the numbers - which are rising fast - of claimants and the amount being spent by government are simply unsustainable. There will be reform as well as cuts — Reeves has identified what she sees as “perverse incentives” in the system.

The government briefing that Rachel Reeves will make large spending cuts this month is very significant, in several different ways.

First, it confirms what had been rumoured - that the Office for Budget Responsibility (OBR), the independent forecaster, believes that the chancellor’s "headroom" has been eliminated. This is the £10bn worth of leeway which, as of last October, the OBR believed the government had before breaking its self-imposed borrowing rules.

Why has that headroom disappeared? The government’s clear view is that this is because of global factors - tariffs being imposed by President Trump, broader uncertainty emanating from the new US administration, persistent inflation in the UK and elsewhere, and the rising cost of government borrowing.

But there will be a big political argument about this. The Conservatives will contend that the cost of government borrowing was rising even before President Trump took office and that the tax rises in Reeves’s Budget in October were a major factor, as well as in stunting growth.

Keir Starmer is now on his feet in the House of Commons, ready for another round of PMQs.

Cheers from the Labour benches as Keir Starmer takes his seat. Shortly followed by Kemi Badenoch. The leaders are cutting it fine this week.

Hello from the press gallery of the House of Commons.

So much has happened since PMQs last week – the prime minister’s trip to Washington, President Zelensky’s trip to Washington, the summit in London on Sunday and the chancellor’s remarks about the public finances.

Lets see where the exchanges take us.

The latest exchanges from today's Prime Minister's Questions will be covered in this page, as well as analysis from our correspondents at Westminster.

This time last week, Keir Starmer arrived at PMQs ready for his journey to Washington DC.

The prime minister planned to take with him the promise of an increase in defence spending to 2.5% of GDP by 2027 - in the hope this might show Donald Trump that Europe was taking the prospect of boosting its defences seriously.

But, touting his plans at the dispatch box, Keir Starmer could not have predicted the collapse in diplomatic relations that soon followed, when Trump and Volodymyr Zelensky clashed in the White House over Ukraine.

Zelensky was told to leave, and is yet to repair his relationship with his US counterpart - though he said yesterday he is ready to work with Trump’s “strong leadership” and “make things right”.

Starmer welcomed Zelensky to the UK for a summit at the weekend - where a plan for a “coalition of the willing” was put forward to solve Ukrainian security concerns in the event of a ceasefire.

One thing that's expected to come up is UK government spending - after it emerged that Chancellor Rachel Reeves is planning to make several billion pounds in spending cuts - including from the welfare budget.

She's expected to announce these in the Spring Statement (an announcement to Parliament on 26 March about her plans for the economy and taxes).

The BBC's economics editor Faisal Islam writes that insiders expect "politically painful" new welfare cuts that are designed to reduce the huge growth in health-related benefits.

The government has committed to get debt falling as a share of the economy during the course of this Parliament, and to only borrow to fund investment, not to cover day-to-day spending.

The plans will first be sent to the government's official forecaster, the Office for Budget Responsibility.

The prime minister has left No 10 and is heading for the House of Commons.

He'll face Conservative leader Kemi Badenoch across the dispatch box at midday.

A lot has happened since the last PMQs, to put it mildly.

Keir Starmer’s trip to the White House, the bust-up between Trump and Zelensky and Sunday’s summit in London producing pledges of European rearmament and talk of a peace plan for Ukraine.

These are dizzying and, to many in Westminster, disturbing times.

But there is also broad cross party support for Keir Starmer’s approach to the crisis so it may not dominate the dispatch box joust today.

Instead, Kemi Badenoch may go on the BBC’s reporting that big welfare cuts are imminent to help plug the hole in the chancellor’s plans.

The Tories will be likely be on board with the medicine - but will argue government policies have made the economy sicker.

What’s clear is that the chancellor’s statement to the Commons on 26 March will be a much bigger deal than originally billed and we may get a taste of that in the clashes this lunchtime.

It's Wednesday which, for politics enthusiasts, can only mean one thing: Prime Minister's Questions.

Like most weeks, the UK's prime minister will be gearing up for a grilling by the leader of the opposition and other MPs at midday.

But, this has been no ordinary week for Sir Keir Starmer, or his counterparts across Europe.

After meeting US President Donald Trump last Thursday, before an extraordinary clash between Zelensky and Trump in the Oval Office on Friday, the Ukrainian president made his way to the UK to attend a summit with European leaders in London.

The discussions led to the announcement of a "coalition of the willing" committed to defending Ukraine.

Trump's address to Congress on Tuesday - where he told US lawmakers that he "appreciates" Zelensky's message on Ukraine peace- will prompt hopes that the two leaders can mend their relationship. But he also announced he will pause military aid to Ukraine which, as our politics correspondent writes, raising the stakes for Starmer.

There will be no shortage of things to discuss in the House of Commons so stick with us for the latest updates.
