A labour leader who was a labour man, unlike Blair, brown and milliband.
I'm not sure what you mean by "a Labour man".
Foot was no more a natural Labour man than Blair, and much less so than Brown and Miliband.
He came from a Liberal family, and attended Leighton Park school in Reading, known as 'the Quaker Eton'.
Like Blair, he was converted to Labour while a student at Oxford, whereas Brown and Miliband were always Labour Party members.
Like many people from posh backgrounds who join the Labour Party, he tended to have an idealised view of the working class, seeing no evil in some trade union practices that, if perpetrated by others, would be deemed indefensible.
In 1975, while he was the Secretary of State for Employment, for example, six men were dismissed from their jobs at Ferrybridge because of the introduction of a closed shop. Not only were they dismissed, but they were denied unemployment benefit.
But Foot showed them absolutely no sympathy.
"A person who declines to fall in with new conditions of employment which result from a collective agreement may well be considered to have brought about his own dismissal," he was reported to have said.
In other words they could starve, and in that sense Foot's socialism was bordering on fascism.
Similarly, he proposed legislation that would have completely neutered a feee press.
But you'll find that if you read Foot's biography of Aneurin Bevan, Bevan could do absolutely no wrong in Foot's eyes.
It was a rather embarrassing hagiography, totally lacking in any objectivity.
