POGS, in response to your post @ 14:07 today (24/03/29) I am pleased you agree with what I stated in my post @ 23:14 on the 23/03/19. However, I believe you over exaggerate when you state that "Labour is of far left / Marxist ideology of the 70's / 80's", which I feel is inaccurate in regards to the present day Labour party.
The parliamentary Labour party now reflects the long-held views of the broader Labour movement in the country which have been consistent over very many years. In that, those grassroots policies have always been to the left of the palimentery party, but compromise was always reached with past Labour governments. However, the Blair years ended the above when that three-term government administration did not revoke one section on the numerous anti-trade union bills brought forward by Thacher and Major, buttered up to the Bankers and launched the Iraq war.
The above set the scene for change in the Labour party with grassroots activists in the broader movement (especially the trade unions) becoming determined they would have a party that spoke for them into the future. The leadership of the Parliamentary party changed inline with the above with the election Jeremy Corbyn as leader which cemented the broader left polices the whole Labour movement is now signed up to.
The above polices are not in any way Marxist or Trotskyist as you state POGs, as they contain only two industries marked for re-nationalisation, that being the rail industry and water supply. That policy when placed in opinion poll canvasing seems to hold broad support with the electorate.
Other policies include bringing to an end the total disgrace of the Gig Economy, greater funding for schools and the NHS, greater regulation of private sector rented housing and the repeal of sections of the anti-trade union legislation brought in by the Thacher and Major administrations.
The above policies are not by any stretch of the imagination Marxist communist, and when asked in opinion polls many people state they would support such an agenda.
In the media this week it was reported that a very wealthy private landlord is evicting a large number of tenant families from their homes in the North of England simply because he and his wife "wish to retire." When that can happen in Britain today with no means of redress for those families, something is very wrong with our society.
The above is why the present Labour movement state they will maintain the above polices and further state those will not change even if the Labour party does not win the next general election.
And that's the way it should be I believe.
