He was called Churchill in a Yankees cap after the Sept. 11 attacks, and if you need to be reminded, Rudy Giuliani was in London today taking questions from Winston Churchill’s granddaughter Celia Sandys.

Should that not be enough, he was to receive the first-ever Margaret Thatcher Medal of Freedom from the Iron Lady herself.

The three-day trip offered Giuliani the chance to press his credentials as terrorism fighter and evoke Reagan’s memory.

And after meetings with Prime Minister Gordon Brown and his predecessor Tony Blair, Giuliani was raising campaign cash from ex-pats in England.

He’s the latest Republican to visit Thatcher and extol the friendship between her and Ronald Reagan.

“That’s one of the strongest relationships that American presidents and prime ministers ever had, between Ronald Reagan and Margaret Thatcher,” he said in comments at 10 Downing Street, according to excerpts provided by his campaign.

The presidential candidate has talked about reading Roy Jenkin’s biography of the British prime minister for inspiration after the attacks.

“On the night after the attacks of Sept. 11, I remember getting home at about 2:30 a.m. and seeing on my nightstand a book I had been reading, a prepublication copy of Roy Jenkins’s forthcoming ‘Churchill,’ ” the former mayor wrote last year in the Wall Street Street Journal. “I picked up this biography of a man who embodied every leadership principle I value—courage, optimism, preparation and a determination to stand up to bullies—and began reading about Churchill’s becoming prime minister in 1940….”

Today, of the relationship between the United States and the United Kingdom, he said: “It is a special relationship that has been forged over many, many years of common objectives, common values. Tested by war. Tested by terrorism.”
