Those endorsing Len McCluskey include the Morning Star, Ken Loach, the Blacklist Support Group, Harry Leslie Smith, and the Durham Miners' Association.

And a Trotskyist, technically so called.
Ian Allinson and I have mutual friends, and I am aware of his good work as a convenor at Fujitsu in Manchester.
But he is behaving in the way that gives Trotskyists a bad name.
