The trade union kingpin used foul language repeatedly during a speech at the Durham Miners’ Gala today that also saw the Unite boss tell Mr Watson he should be “should f***** be ashamed” of himself over criticism he faced for condemning party general secretary Jennie Formby, who is battling breast cancer. After the speech, Mr McCluskey – who has a child with Mrs Formby – repeated his tirade on Mr Watson on Twitter. He said: “I’ve said it today at the Durham Miners Gala so I’ll repeat it here. Attacking a woman going through chemotherapy Tom Watson you are a f***** disgrace.”
The abuse comes as Mr Watson penned a letter to Mrs Formby condemning her response on behalf of the Labour Party to allegations of anti-semitism aired during a BBC Panorama episode.
A total of eight people told the programme they were undermined in their attempts to tackle anti-semitism in the party.
Mr Watson said the people who spoke to the programme were “very brave to go before a camera and tell their stories”.
He said: ”The way that they have been smeared, including by Labour spokespeople, is deplorable.
“Even if some in the party did not want to hear what they had to say, it is unacceptable to attempt to undermine their integrity and characters in this manner.”
Labour’s shadow chancellor John McDonnell backed issuing non-disclosure agreements (NDAs), seen as an attempt to silence those wanting to speak about the claims.
Panorama discovered there was a backlog of 1,000 anti-Semitism allegations over the last few months, with only 15 people having been expelled.
Labour leader Mr Corbyn has since said there were “many, many, inaccuracies” in the BBC Panorama documentary shown Wednesday.
Also speaking today at the gala, he said: “I watched the programme and I felt there were many, many inaccuracies in the programme.
“The programme adopted a pre-determined position on its own website before it was broadcast.
“We’ve made very clear what our processes are.
“Our party members do have the right to be heard if they’re accused of anything and our party staff have a right to be supported and they are supported.”
