EX-PM Gordon Brown revealed Vladimir Putin belittled him by making him sit on a small chair on an official visit to Moscow.
Describing the Russian tyrant’s bullying for the first time, Mr Brown, 71, recalled their 2006 meeting when he was then-PM Tony Blair’s Chancellor.
He said: “I was under no illusions about what Putin was like. I was put in a very low seat so that I was looking up at him.
“He’s certainly a relatively small man and he wears these stacked heels.
“That day he took out these index cards, and proceeded to read out all this information he had about me as though he wanted to prove he knew more about me than I knew about myself.
“So when people say Putin’s changed and is only now threatening, I can tell you he was threatening me even then.”
Mr Brown told the Telegraph Putin responds only to “an uncompromising and unyielding show of strength”.
He added: “Weakness he will exploit. He’s opportunistic to the nth degree.”
The Labour bigwig yesterday blasted the West’s inaction over Russian action in Donbas and Crimea in 2014 when Tory David Cameron was PM.
It came after Britain’s top general, Sir Patrick Sanders, warned British soldiers must be ready to fight Russia.
