Jeremy Corbyn has admitted he was "unaware" of the size of the student loans debt when he said he would "deal with it" during the general election campaign.

The Labour leader said in June that he wanted to look at ways to deal with "the massive debt" of school leavers and "reduce" the burden of existing student debt.

He has faced claims he used students as "election fodder" by indicating he would wipe out the sums they owed for their education.
