Brexit was the overriding debate in the recent general election, and for the Labour Party it proved to be an unbridgeable divide between its traditional supporters in the North who were in favour of Britain leaving the EU and its southern England remain Supporters. However, that is now all water under the bridge.
Following the loss of the 2014 general election, the Labour movement was very much on the verge of tearing itself apart. Years of allowing Blair and Brown to turn "New Labour" into an organisation which had become very detached from the broader labour movement in the country had proven to be a failure. The Parliamentary Labour Party was still very reliant on funding by way of the affiliation subscriptions of trade union members, while its polices in no way subscribed to the wider employment ambitions of those working people and their families.
Jeremy Corbyn realised the above, and in that got elected as Labour leader and from that position returned the Parliamentary Party to being a core integral sector of the broader Labour movement with policies in line with its traditional core values.
In the above, it may well be that in the forthcoming year's historians may look upon Corbyn as the person who saved the Labour movement from destroying itself. However, moving the Parliamentary Labour Party back onto a left-wing stance caused dissension within a number of right leaning Labour MPs that Corbyn always felt he could come to terms with. Sadly, and in the end, history may well also demonstrate that Jeremy Corbyn did not act hard enough on those dissenters, and that contributed to the electoral losses.
Whoever becomes the new Leader of the Parliamentary Party there can be, and will not be, any return to the days and policies of Blair and Brown. Buttering up to Bankers, non-dom tax exiles and the likes of Rupert Murdoch will never again be acceptable in any part of the Labour movement, of that I am sure
Therefore, Labour should remain on a strong left wing platform into the future, and if and when Brexit, deregulation and unbridled capitalism hit working families hard, then just remind them it was such that the majority voted for in 2019.
