Jeremy Corbyn deployed one of his trademark teacher-style 'looks' during prime minister's questions on Wednesday, in the face of sustained heckling from the Conservative benches.
The Labour leader, who has developed a good line in stern glares, stopped mid-flow to ask Tory MP Gavin Williamson: "are you done?"
Williamson is parliamentary private secretary (PPS) to David Cameron. John Bercow intervened to tell him to be quiet. "Calm yourself man," he said over the noise of PMQs. "Auditioning to be a statesman doesn't include chuntering from a sedentary position."
