The Tories and Lib Dems have called on Justice Secretary David Lammy to return to the House of Commons to answer questions on the accidentally released foreign offender.
It comes after he dodged questions from the shadow defence secretary during deputy Prime Minister's Questions this lunchtime.
Tory leader Kemi Badenoch's spokesman told reporters: "I think he should a statement as soon as possible."
He added: "I think, given that he had five opportunities to tell the House and the public what the hell was going on and ducked those opportunities, he needs to come back to the House as soon as possible."
The Lib Dems' justice spokesperson Jess Brown-Fuller MP also joined the calls, saying: "This is yet another grave mistake from the government. The public deserves a full explanation about how this happened again.
"This should start with David Lammy coming before parliament this afternoon for why he failed to answer this pressing question in PMQs as well as a full explanation of how it took almost a week for this to come to light."
She added that the situation "would be laughable if the situation weren't so dangerous".
