I think Labour are still the riskier option, just.
The 7p per meal gaffe is insane (just asking someone to work the extra hour will cost 30-50p per meal if nothing else)...
But Labour want to heavily increase taxation, heavily increase spending, and nationalise things all over the place. Whether or not you support that idea, it's a huge change, with the potential to go very badly (for example, if increasing corporation tax and the highest tax rate moves jobs abroad).
On the other hand the Tories want to eject us from the Single Market faster than Theresa May can back-track on any cuts affecting Tory voters.
On the other hand, Labour's EU proposals are as clear as mud.
