Corbyn unwisely brings up Cameron’s anti-cuts mum at PMQs, Cameron blows him away with a dynamite comeback:

“I know what my mother would say. She’d look across the despatch box and say, put on a proper suit, do up your tie and sing the national anthem.”

The Labour benches silent, Lammy with his head in his hands, as Watson and Eagle try to keep a straight face…

UPDATE: Corbyn eventually thinks of a comeback:

“If most of us are ashamed of shabby clothes & shoddy furniture let us be more ashamed of shabby ideas & shoddy philosophies" Einstein #pmqs
