Labour has painted itself into a corner that it can't get out of.

The Labour Party membership elect "The Leader", come any General Election he naturally will be the Prime Minister should Labour win that General Election. If the majority of those who have flocked to become members of the Labour Party are hard left "Socialist Workers Party" then "their" man wins the Leadership election. Unfortunately the 670,000 members of the Labour Party cannot get their man into Government for that they need the votes of those who traditionally vote Labour and at the moment under Jeremy Corbyn those "traditional labour voters" will more likely as not vote for UKIP or "Independent" candidates if "Momentum" deselects good existing constituency MPs because they challenged Jeremy Corbyn's "leadership".

Kevin if you end up with a Conservative Government for the rest of your life it is because the Labour Governments of the past have failed to do anything that they promised the electorate. In general in elections, political parties in opposition don't win elections, sitting Governments lose them because they have failed to deliver.
