Nick Robinson is suggesting that Boris Johnson may run for London mayor. I can tell you that Boris was unofficially sounded out at the Tory summer party last year, and resolved he didn't want to give up his superb, safe and beautiful Henley seat (which they told him he'd have to do). As of last month, he was asked again and hadn't changed his mind. But in light of the tragic news of Nick Boles’ illness, might things have moved on? I doubt it. But I'll keep you posted.
