McSweeney was not a creature of Sir Keir Starmer's. It was the other way around.
McSweeney was a creature of Mandelson.
McSweeney persuaded Sir Keir to seek the leadership as a way of getting rid of the far left leader Corbyn who had almost won the 2017 general election.
From an article in the Electronic Intifada about McSweeney and his fierce devotion to Israel:
In November, Health Secretary Wes Streeting – a stalwart in the pressure group Labour Friends of Israel – said that “there wouldn’t be a Labour government without him.” Journalist George Eaton wrote that the current Labour cabinet “more than ever, is made in McSweeney’s image.”
Young McSweeney did not act alone. I am sure Mandelson stood at his shoulder .
It was a reprisal of his and Mr Blair's attempt to prevent Brexit. Mr Blair probably advised about this.
Probably MI5 were involved, perhaps closely.
Were the intelligence services of other countries involved?
Of course.
Mandelson, we know, was feeding confidential information to Epstein, who was working for israel.
Corbyn represented an enormous security threat to lots of countries, as he was anti-American, anti-Nato and anti-Israel.
Westerners now live in an Epsteinian world and guess at the hidden hands of intelligence services.
Eastern Europeans always knew the world was like that.
