They can't lose that Zlatan, as I've expained before, the Labour party was formed out of trade unionism and the unions have to be their paymasters. It takes lots of money to run a political party and unlike the Tories, the party has few wealthy private backers.
They can only lose the trade unions if they lose the Labour name as well, but if they are the same people, would anyone believe them? And would the Tory media machine let the people believe them? The answer to both of those is an emphatic NO.
The best they could do would be like the 2017 GE result, looking much better but still far short of a win without the Scottish vote that they used to enjoy. We don't have a Labour electorate in England that's anything like sufficient to win without Scottish and Welsh Labour dominance.

Fair point, but the Union control could be reduced. If anything Union control has increased. McCluskey has way more power than is generally assumed. He is almost the king maker within the party. It was his support for Ed over David that set the party on its deeper swing to left. McCluskey still supports Corbyn and sees Starmer as Blair Junior... Hence current problems.
As far back as sixties Wilson thought it necessary to curb powers of Union which to some extent he achieved.
The Labour Party needs Union funding as Tories need their contributions but the power Unions hold over Labour is far greater almost by definition. It's a Union, Unite is biggest in Europe (I believe). Tory funding is more fragmented and hence less direct control. The formation of Unite was in my mind a political mistake. Unions should be diverse, representing individual groups and not a political body to exert control directly of electorate via a Party
The Unions are getting 2 bites of cherry as its organised. They chose Labour leader and then walk to polling booth and vote for same person. That can't be right.
People, rightly or wrongly, do not want unions controlling power. Assume we got a Labour Government. McCluskey becomes most powerful person in the country. Because he is head of Unite and as far as electorate concerned not democratically elected. That is wrong.
The "real Labour" party should represent electorate and not union members. (as was explained in Dominic Lawson article)
