I had heard rumours of 50bil or so, but Boris is saying 30bil is too much, I think.

All of which is very puzzling because I've been assured many times that Brexit means Brexit and that that answers all questions pertaining to the details of us leaving the EU so I'm not too sure what the issue really is.

I'm going to repeat Brexit means Brexit over and over to myself and see if a number magically appears at some point.
