//Can you think of a rational reason for Central Office or the local party (whosoever decides these things) to allow this man to stand, NJ?//
No I can't.
//Here you and I must disagree, NJ. There are some unanswered questions, not chiefly why the 'disgraced' Tory candidate was reselected. He must have had something going for him. I suspect the recall was entirely at the behest of the opposition.//
The recall was triggered by 10,000 (20%) of constituents voting for it. Nobody knows the makup of that 20%. Mr Davies polled 20,000 votes last time out and 12,400 this. His missing 7,600 cannot all be attributed to the Brexit Party (who only polled 3,300 in total). Quite frankly, any party who puts up a candidate who has two very recent convictions for fraud against the public purse and who was removed from the seat precisely because of those convictions deserves to see their candidate lose his deposit.
