I didn't bother taking much notice of the previous post when I saw it was quoted from 'The Sun'
Anyway, if you really want May 'to quit whining, grow a pair and be competent at her job' then you shouldn't moan if she does grow a pair and tells the EU to get lost.

She could also tell the 'dissenters' to shut up or she'll replace them with Pro Brexit people . . the door is over there . . .
Not that she's stupid enough to do either of those, because she knows she'll get slammed by the public & media for being 'a
bully strong character'
