Could one happen once A50 is triggered?
There have been calls from various places and I have read some good articles arguing for.
May appears to be popular with the public. The Tories are way ahead in the polls. She could silence he 60 or so rebels. An election now would reduce Labour to a rump. She only has a slim majority when the Brexit negotiations start so an election would give her a thumping majority and put her firmly in the driving seat.
It would require repeal of the Fixed Term Parliament Act, but that should be no problem as many MPs feel it ties them (in government) down too much.The many positives and few negatives must make it very tempting.
