As Sir Keir Starmer can tell Andy Burnham when they pass each other going out and coming in, campaigning for office is very different from governing. Mr Burnham has made an impressive pitch to be prime minister, an opportunity for which he has been preparing for more than a year, as his campaign manager Louise Haigh admitted this week.
