A manhunt is under way for a second migrant who has been wrongly freed from prison.
An Algerian man, 24, was accidentally released from HMP Wandsworth in south London on Wednesday last week.
However, the Metropolitan Police was only informed at lunchtime on Tuesday.
The news emerged as David Lammy, the Deputy Prime Minister, refused to answer multiple questions from James Cartlidge, the shadow defence secretary, at Prime Minister’s Questions on whether any other migrant had been mistakenly released.
