Boris Johnson moaned that Keir Starmer wouldn't stop asking questions about mass deaths and starving children in Yemen - and the UK's sales of billions in arms to Saudi Arabia to use in the conflict.
As the government prepares to slash aid to help those devastated by the brutal civil war by 50%, the PM complained that the Labour leader didn't ask him questions about how well the Covid-19 roadmap was going.
He said: "He can't even address a question on the issues of the hour. He could have asked anything about the Coronavirus Pandemic, instead he's concentrated his questions entirely to the interests of the people of Yemen."
Starmer pressed Boris Johnson on whether arms sales to Yemen should be suspended.
Opening PMQs, Sir Keir said: "Does the Prime Minister agree with President Biden that the sale of arms that could be used in the war in Yemen should be suspended?"
The Prime Minister replied: "Ever since the tragic conflict in Yemen broke out this country has scrupulously followed the consolidated guidance of which (Sir Keir Starmer ) will be well aware."
But Mr Starmer said the UK is "increasingly isolated" in selling arms to Saudi Arabia.
He said: "(Mr Johnson) says the system's very robust in relation to arms sales, it can't be that robust, the Government lost a court case just two years ago in relation to arms sales.
"The truth is the UK is increasingly isolated in selling arms to Saudi Arabia. Despite what's happening in Yemen, despite Saudi Arabia's human rights record and the brutal murder of journalist Jamal Khashoggi, a murder the US has concluded was approved by the Saudi Crown Prince.
"So I have to ask, what would it take for the Prime Minister to suspend arms sales to Saudi Arabia?"
Mr Johnson responded: "We've condemned the murder of Jamal Khashoggi, we continue to call for a full investigation into the causes of his death and indeed, we have already sanctioned 20 people in Saudi Arabia.
"And I repeat the point that I have made that the UK Government continues to follow the consolidated guidance which, by the way, was set up by the Labour Party."
The PM insisted the British people can be "hugely proud" of the country's support for Yemen.
MR Starmer said: "The trouble is that whilst President Biden has suspended arms sales that could be used in Yemen, the UK hasn't. In fact, we sold £1.4 billion of arms to Saudi Arabia in the last... in three months last year including bombs and missiles that could be used in Yemen.
"Given everything we know about the appalling humanitarian cost of this war with innocent civilians caught between the Saudi coalition and the Houthi rebels, why does the Prime Minister think it is right to be selling these weapons?"
Mr Johnson replied that the UK Government "continue scrupulously to follow the humanitarian guidance which are amongst the toughest measures anywhere in the world in respect of all arms sales".
He added: "He talks about humanitarian relief and actually I think the people of this country can be hugely proud of what we are doing to support the people of Yemen - almost £1 billion of aid contributed in the last five years."
But Mr Starmer demanded the PM explain how he can justify a cut in aid to Yemen while selling arms to Saudi Arabia.
He said: "To make matters worse the Government decided this week to halve international aid to Yemen - halve it.
"The UN has said that Yemen faces the worst famine the world has seen for decades and the secretary general said on Monday that cutting aid would be, in his words, a death sentence for the people of Yemen.
"How on earth can the Prime Minister justify selling arms to Saudi Arabia and cutting aid to people starving in Yemen?"
Mr Johnson responded: "It is under this Government that we have increased aid spending to the highest proportion in the history of our country and yes, it is true that current... circumstances, which I'm sure the people of this country understand, mean that temporarily we must reduce aid spending.
"But that does not obscure the fact that when it comes to our duty to the people of Yemen, we continue to step up to the plate."
