The head security firms G4S and Serco have apologised to MPs after overcharging the Government by millions for tagging offenders. The firm had its offer to repay the money rejected by the Government yesterday.
Taxpayers will get "a refund" on the £24 million G4S wrongly charged the Government for monitoring offenders, according to the Ministry of Justice (MoJ).
An MoJ spokesman said it was still working with the firms and the independent auditors to work out "what the final sum will be".
The head of G4S is due to appear in front of MPs at the public accounts committee later today:
The Secretary of State has been clear: we are determined to secure a refund for the taxpayer.We have taken appropriate legal advice and will pursue all possible avenues. This matter is now the subject of a criminal investigation.
We are not able to comment further at the current time. We will make a further statement when it is appropriate to do so.
