Diary – 25 February 2016

The Prime Minister is pretty angry with Boris. But the idea that they’ve competed with each other since school is wrong. Boris is two years older than Cameron — and differences in age are like dog years when you’re young. When I was 13, 15-year-olds seemed like grown-ups, 6ft tall with three days’ growth. When I interviewed Cameron last year, he said he’d hardly known Boris at Eton because he was in College — the scholars’ house — and two years above him. Cameron did remember Boris on the rugby field because he was so dishevelled and ferocious. And he watched him in a few debates at the Oxford Union. But that was as close as they got in their youth. I asked Cameron if there was anything in the idea of these two boys vying to be PM. ‘It would make a great book but it’s not true at all,’ he said.
