"Labour warned that the Government was taking risks with Britain's security by not fixing the reserve recruitment crisis before reducing numbers in the regular Army. We specifically raised the worrying IT problems and Capita's performance as causes for concern. But the Government recklessly pressed ahead.
"Now we learn that the problems were worse than anyone thought and still haven't been fixed. The blame for this latest fiasco - which is wasting £1m of taxpayers money every month - lies squarely with government. Philip Hammond needs to get a grip and sort this shambles out."
The Army is being cut from 102,000 to 82,000 by 2020 while the newly-renamed Army Reserve - formerly the Territorial Army - is being expanded from 19,000 to 30,000.
In a paper lodged in Parliament in December Mr Hammond said that recruitment in 2013 "has been well below historic levels" and acknowledged there were problems with the IT system.
An MoD spokeswoman said: "In December last year we acknowledged a number of problems with the Army and Capita recruitment partnership. Ministers have gripped these problems and put in place a number of fixes to correct the issues that had emerged.
"As we have previously said, in the medium-term we are building a new IT platform that will be ready early next year and in the short term we are introducing work-arounds and mitigation measures to the old IT platform to simplify the application process.
"With an improved Army recruitment website, streamlined medicals and an increase in the number of recruiting staff, recruits should see a much improved experience at the end of this month."
