Under-fire Suella Braverman was told she had "broken the law" as Rishi Sunak struggled to defend her in a furious PMQs clash.
The Home Secretary scowled as she was hauled over the coals by senior Labour MP Meg Hillier, who accused her of leaking information, presiding over "chaos" in the Home Office and "breaking the law".
Ms Hillier, who chairs the Commons Public Accounts Committee, blasted: "What will she actually have to do to get the sack?"
The Prime Minister battled to defend Ms Braverman, who he reappointed as Home Secretary only six days after she was forced to resign for a serious breach of ministerial rules.
He retorted: "The Home Secretary made an error of judgment but she recognised her mistake and took accountability for her actions."
Ms Braverman has set out "transparently, in detail, a full sequence of events", he said, after it emerged she sent sensitive draft immigration policy to Tory backbencher Sir John Hayes from a personal email account and accidentally copied in a Tory staffer.
Mr Sunak said: "She is now getting on with the job - cracking down on crime, defending our borders, something I know the party opposite has no interest in supporting."
But questions about the crisis-hit Home Secretary's conduct continued during an increasingly fractious PMQs session.
Keir Starmer ripped into the Government for claiming the asylum system is broken after more than a decade of Tory rule.
The Labour leader said: "His Home Secretary says the asylum system is broken. Who broke it?"
To angry shouts from the opposition benches, Mr Sunak said: "We can look at the record on migration policy... What did we on this side of the House do?
"We gave the British people a referendum on Brexit. We delivered Brexit. We ended the free movement of people. That's our record on migration policy."
He then claimed Mr Starmer had "opposed [ending freedom of movement] at every turn and it's not what the British people want."
The Labour leader hit back: "No-one wants open borders on this side of the House. They have lost control of borders on their side of the House.
"Four prime ministers in five years. It's the same old, same old, he stands there and tries to pass the blame.
"If the asylum system is broken, and his lot have been in power for 12 years, how can it be anyone's fault but theirs?"
Mr Sunak replied: "Border control is a serious, complex issue, but not only does the party opposite not have a plan, they have opposed every single measure we have taken to solve the problem, you can't attack a plan if you don't have a plan."
But he was forced to admit that "not enough" asylum claims had been processed.
Pressed on the issue by Mr Starmer, he replied: "Not enough is the answer, very straightforwardly, not enough. That's what we are going to fix. But the honourable gentleman raises this question, what do we do? We have increased the number of processing officials by 80%.
"We are putting an extra 500 more by next March. But if he really was serious about fixing this problem, then he would acknowledge that we do need to tackle the issue of people putting spurious, spurious claims, spurious repeated last-minute claims to frustrate the process. That's how we'll tackle the system."
