The Tory manifesto includes 60 pledges that are totally uncosted. This includes increasing R&D funding, £1bn extra for prisons, increasing school budgets by £4bn, dementia research, increasing defence spending, 1 million trees, a completely vague "cultural development fund", more low-emission buses, moving civil servants out of London, increasing funding for TEFL, training one million people in mental health awareness, etc etc...
These go on and on and on and have no costing whatsoever. None. No indication about where the money for any of these is going to come from. And that's before you get to biggest omissions - i.e. how much their immigration target would cost and where the axe will fall on means testing WFA.
Labour have costed their promises to a far greater extent. Furthermore this chartered accountant has actually taken a look at the UK's debt history under the two parties and put the data right in front of the reader:

Not only do Labour consistently borrow less, they also pay off significantly more of our debt on average when they are in office. Meanwhile the Tories have ENORMOUSLY increased our debt since 2010 (though it had been going up since 2008 for obvious reasons):

As soon as you actually look at the facts rather than run on political autopilot, it becomes clear that this idea Labour are somehow the ditsy spendthrift party is a load of politically-charged nonsense.
