Not many people know Dave Ward, but he's a big bluff chap who has a day job as the general secretary of the Communication Workers Union (CWU).
But the other day Dave was given the task of announcing that some faceless committee of his trade union had decided to throw its 'weight' behind Jeremy Corbyn is his effort to become the next leader of the Labour party.
So far so boring, and while relatively few CWU members will share Jeremy Corbyn's views about politics the sting was in the tail of Dave's announcement in which he said:
“I am delighted to announce that the CWU will be backing Jeremy Corbyn MP to be the next leader of the Labour party. There are no quick fixes for the Labour party, but there are some easy decisions, and choosing Jeremy as its leader should be one of them.
“We think that it is time for a change for Labour. The grip of the Blairites and individuals like Peter Mandelson must now be loosened once and for all. There is a virus within the Labour party, and Jeremy Corbyn is the antidote.
Now to describe fellow Labour members as a 'virus' which must be eliminated from the once proud 'People's Party' strikes me as a new low in what passes for political debate these days.
Because I enjoy a bit of political knockabout as much as the next person, but this buffoon is actually calling for other supporters to be driven out of the Labour party, presumably so that they can go off and support a political rival.
Which seems like a strange way to win friends and influence the voters.
The whole nasty business reminded me of a cult movie from the 1960s - The Satan Bug - which tells the tale of a mad scientist who steals a deadly virus (the Satan bug) that has the potential to destroy the human race.
If you ask me, the Labour party seems intent on destroying itself from within if people like Dave Ward are anything to go by and isn't it noticeable that old Labour stalwarts like Lord John Prescott have nothing to say about this kind of destructive behaviour.
Dave Ward's statement on Twitter was accompanied by a YouTube video which readers can view here if you would like to hear one of Britain's union bosses (Bubs) shooting himself and the Labour party through both feet.
Because unless I've been living on a different planet for the past five years since 2010 the Labour party was being led by Ed Miliband, who presented himself as a break with New Labour, yet Ed crashed and burned in the most spectacular fashion at the recent 2015 general election.
So maybe there is a political 'Satan' bug at work here - one which is likely to consign Labour to the political wilderness for years to come.
