30 years ago, Tony Benn, the grandfather of the far left in Britain, almost broke the Labour party in two.
Thankfully, for the party at least, Dennis Healy, saved the party from oblivion.
Now the party faces a new threat of being ripped apart, but with an old face, Jeremy Corbyn.
Jeremy is doing what Benn couldn't all those years ago, he tearing the party in two, and I have to give credit where it's due, he's doing it very well.
Ever since he became leader of the Labour party, I have new found respect for many Labour MP's I once despised.
Yvette Cooper, Hilary Benn, Chris Lesley, Ben Bradshaw, John Mann, Mary Creagh, are to name but a few.
They've all taken a leap out of their new leaders book, they're standing by their views, and rebelling against Mr Corbyn, and they're rebelling loudly.
Funnily enough, it seems now the shoe is on the other foot, he's not so keen on rebelling as he used to be at the beginning of the year, strange that isn't it?
