To tell the truth pup I have no idea who can unite the party. Present one is far too left for my liking, I'm Centre Labour, a moderate that often leans ever so slightly left depending what's on offer. I'm quite capable of seeing two sides to every debate.
Do like Kier Starmer although I reckon the next leader could well be a woman.
Meanwhile in fawlty towers hand wringing May or May not get a Brexit deal is presiding over one of the most mediocre Tory Governments I can remember, with very little opposition to give them a good ' kicking '
Labour Party need to look more to Public / Private ownership rather than wholesale Privatisation.
EDIT : Tony Blair 97 to around 2003 got it right, unfortunately he went too far right for my liking, he did however unite the Party for a short period of time.
