This is ... possible, yes. I proposed she did that for Bremainers, but yes, it could be she did so for Brexiteers.

Boris Johnson just rejected any payments into EU budget again. Giving cash to EU is just about the only leverage UK has at this point. Does he really think he can extract concessions without giving anything in return?

Probably not, but for the vast majority of Conservatives it is more important not to pay into EU than get a decent Brexit deal.
