Priti Patel faced fury today after she refused to face MPs over a computer debacle that saw hundreds of thousands of vital records wiped from a police database.
The Home Secretary sent her deputy, the Policing Minister Kit Malthouse, to the Commons after a significant number of fingerprint, DNA and arrest history records were lost due to human error and defective code.
Initially, some 150,000 records were believed to have been affected, but it has emerged the number is far higher than first thought at about 400,000.
Ms Patel earlier posed for pictures with police officers in Westminster and said everyone was working flat out to solve what she said was a 'technical coding error'.
But it was left to Mr Malthouse to face political fury from opposition parties this afternoon. He revealed the Home Secretary has commissioned an internal review.
Shadow Home Secretary Nick Thomas-Symonds said: 'I must ask, where is the Home Secretary? The loss of hundreds of thousands of pieces of data, data so important for apprehending suspects and safeguarding vulnerable people, is extraordinarily serious.
'It was the Home Secretary who needed to show leadership and take control. It's what previous home secretaries have done in a crisis - on the passport office, on Windrush, on knife crime, whatever their mistakes, home secretaries came and answered to this House, they didn't just offer a media clip as has happened today.
'This Home Secretary failing on violent crime, failing on the Windrush compensation scheme, with chaos on border testing, found to have broken the ministerial code, now won't even answer to parliament and the public on this most serious of issues.
'The Home Secretary likes to talk tough, but when the going gets tough, she's nowhere to be seen.'
