Tony Blair has released a statement about his "remarkable" father Leo, who has died aged 89:
He was a remarkable man.
Raised in a poor part of Glasgow, he worked his way up from nothing, with great ambitions dashed by serious illness on the very brink of their fulfilment.
He lost my mother, whom he adored, when she was still young.
Yet despite it all he remained animated by an extraordinary spirit that was in him until the end.
I was privileged to have him as a Dad.
