This picture, gives an indication as to why the borrowing took place...
If you look at the dips following a major economic crisis, i.e. 1991/2 and 2008, then you will see that borrowing goes up before coming down again, this is expected. The worst Chancellors we have had in the period shown have been Lamont, Darling and Brown, though Brown was a decent Chancellor early on, the second half of his reign was dreadful as he did not stick to his own economic principles.
The Tories have followed the downward curve on borrowing since 2010, Labour would have had no option but to borrow at a similarly high level if they had won the 2010 GE and their plans actually called for more borrowing than the Tories did.
To use arguments like
"the latest Tory government has borrowed more than all Labour governments in history" is to completely ignore that they had no choice in the matter. They cannot have not borrowed, they had to finance the majority of existing public spending requirements somehow.
We need to cut the deficit in order to start cutting into the debt, which the Tories are doing, albeit slower than anticipated. In comparison the policies of a Labour led administration would have had even greater borrowing and been even further away from reducing the deficit.
