There were lots of jeers and howls of outrage from Labour and Conservative MPs as the PM and Badenoch clashed over the China spying case.
There were accusations, and counter accusations, but no consensus on who’s ultimately accountable for the collapse of the case.
As expected, Badenoch used all of her questions to press the prime minister on the collapse of the case.
“He should have seen this case through,” she said,
She framed it as a national security issue, suggesting the government’s handling of the case means Labour ministers can’t protect the country.
But the PM said the Conservatives were to blame for not labelling China a threat when they were in government.
He said the Conservatives were just “slinging mud”.
With witnesses statements due to be published, this row looks set to continue bubbling away.
