Iam64, Callistemon, in regard to your earlier posts in this thread, I do not feel I and many others are being complacent with reference to the present status of the Labour Party.
Indeed, I would again agree with others that Jeremy Corbyn is certainly no great Parliamentary speaker or group control expert. However, Corbyn has through his leadership completely reformed the organising structure throughout not just the Labour Party, but also throughout the whole broader Labour movement in the country to create one Labour identity.
The above will undoubtedly be Corbyns legacy to the movement and in that is to be found the reasons why so many hold total allegiance to Corbyn through "thick and thin." In short, the Labour grassroots activists both party members and affiliate members now have a full say in policymaking and the day to day running of the party and wider movement, and that they greatly appreciate.
Of course, the above is publicised little outside the activities of the party, and does not win the allegiance of very many left-leaning members of the electorate which is so often demonstrated on social media sites.
However, Jeremy Corbyn has stated he will step down as leader as soon as the Brexit crisis shows any sign of being resolved, (but that could be some way off). There is also within the party and broader Labour movement a resolve I feel to "bring to book" those in the Parliamentary Party that have never accepted the new more democratic organising structure, and in that the election of Jeremy Corbyn as leader.
The above may see many constituency Party deselections of sitting Labour Party MPs that will obviously attract much publicity in Britains right-wing owned press. However, and as stated, many believe the above has to be carried out whatever the cost so that the continuous "wrecking tactics" maintained by some Labour MPs in the Parliamentary Party over the past three years will never be witnessed again. Therefore, I cannot see Jeremy Corbyn giving up the leadership of the party until that action by the constituency parties (where required) is completed.
The above (hopefully) will come about prior to any General Election being called enabling all Labour Parliamentary candidates to support both policies and leader in that election.
So, I would agree like many that a new Party Leader with perhaps more charisma will be required in the face of Corbyn stepping down. That stated, I certainly do not feel that there will be any change of policies or organisational structure in the Labour Party or broader movement, and whoever is elected to replace Corbyn will be much in his image.
