Anthony Seldon discussing Gordo in The Daily Telegraph (emphasis mine):

"I have tried to be balanced about both sides," says Seldon. "But Brown after 2001 doesn't come out of this book well. In some ways his personality resembles that of Edward Heath: brooding, hectoring, introverted. He was undoubtedly wronged by Blair over the succession – Blair broke his promise to hand over to Brown in the second term – and was clearly the more brilliant of the two intellectually. But while Blair grew in stature during his premiership, despite the setbacks, Brown emerges as a diminished figure."

Quite. And he's Edward Heath in another way too.

He's shit.
