[on the Brexit referendum] History will judge Cameron [
David Cameron] as the worst post-war prime minister, she'll [
Theresa May] be the second. Because he lost it, he lost it on a tactical gamble which he thought would work for his party. He lost the premiership, his party is in tatters, he's plunged Britain into a crisis and he never intended any of that. No one has probably made such a catastrophic decision as a prime minister since Lord North lost the US colonies in the 18th century.
