Burnham’s vibe shift gives Labour one more chance but voters also need hope

The prospective new prime minister will need to deliver on his ability to communicate - and get the big decisions right

When Keir Starmer welcomed Mark Rutte, the Nato secretary general, outside No 10 on Monday, the attire fitted the moment: dark formal suits, polished leather shoes. Almost 200 miles to the north, when Andy Burnham strode into the engine hall of the People's History Museum in Manchester, the vibe could not have been more different.

Dressed in his trademark dark T-shirt and jacket, Burnham could just as easily have been walking down the street outside. He even began with a joke about his thigh-skimming running shorts, after he was pictured going for a jog the morning after announcing his return to parliament, telling the assembled audience he had bought a new pair as it was either do that or change the decency laws".
