Jeremy Corbyn’s best performances come when he speaks with the voices of others. Going for the traditional attacking and braying of PMQs leaves him badly exposed, allowing David Cameron to attack him on 30+ years of articles for the Morning Star, appearances on Russia Today, and any number of unsupportive remarks from Labour politicians, both retired and currently in Parliament.

“If JC attempts any kind of cut and thrust *at all* he will get shredded by DC for his own various positions,” reflected one of the team tasked with briefing the Labour leader before PMQs. Corbyn’s new approach to PMQs – of bringing public questions – have a double bonus: they are a living embodiment of the “new politics” that the Islington North MP promises and they make it much harder for Cameron to reply by attacking Corbyn’s record.

It’s a defensive tactic, but the occasional win in the old style is more than wiped out by the damage to Labour and Corbyn by allowing Cameron to play “Red Scare” in the House.

It’s no coincidence that Corbyn’s better PMQs have come when he uses the new-style and his worst when he attempts the old. Until today, the Prime Minister has seemed flummoxed by how to respond to the Labour leader’s use of real people at the despatch box.

But today he finally managed one, skilfully re-appropriating “Rosie”, a young Londoner who is being hit by the capital’s skyrocketing property and rents, in order to praise the government’s record – such as it is – on housebuilding. If you look at the small print, Cameron’s answers left much to be desired: he talked about people like Rosie working to pay the housing benefit of others, a benefit that largely goes to people in work. He praised a fairly indifferent record of housebuilding – that falls far short of where Britain’s housing stock needs to be even to stand still.

However, the Labour leader was incapable of pinning him down. With the old approach to PMQs a non-starter against Cameron, and the Prime Minister finally finding a way to live with the new style, a third way may have be found.
