Today's PMQs descended into a war of words between the views of the Prime Minister and Leader of the Opposition's own mothers. As Corbyn highlighted the problems with Cameron’s own local health service, he asked the Prime Minister: “Will the chair of the Oxfordshire anti-austerity campaign be writing a letter to himself?” At which point Angela Eagle and Carolyn Harris, two Labour MPs, called out “ask your mother", in light of the news last week that Cameron’s own mother signed a petition campaigning to save cuts to local services. In response Mr Cameron hit back: "I think I know what my mother would say, I think she'd look across the Despatch Box say 'put on a proper suit, do up your tie and sing the national anthem!' After much jeering and laughter from the Tory backbenches, Mr Corbyn responded: "If we’re talking of motherly advice, my late mother would have said: ‘stand up for the principle of a health service free at the point of use for everybody’ because that’s what she dedicated her life to, as did many of her generation." The attack delighted Tory backbenchers who cheered uproariously for more than 30 seconds. But Labour MPs were quick to condemn Mr Cameron for hitting a "new low" during Prime Minister's Questions. Nasty personal attack on @jeremycorbyn was beneath the Prime Minister. #PMQs hit a new low today. — Wes Streeting MP (@wesstreeting) February 24, 2016 Cameron might think he's got the funny jokes, but Junior Doctor dispute is serious matter. #pmqs — Toby Perkins (@tobyperkinsmp) February 24, 2016 A senior Labour source later said: "I think when you are losing an argument, you resort to personal insult. When you are not able to answer questions on the NHS, you resort to silly insults. It's got no place in politics." The source said Mr Corbyn had "several suits", adding: "I don't think he will be taking sartorial advice from David Cameron or his mother." Education Secretary Nicky Morgan defended the PM's decision to hit out at Mr Corbyn in response to the jibe about his mother. She told BBC Radio 4's World At One: "What was really noticeable on Monday during the EU statement was that Jeremy Corbyn's top button was not done up, his tie wasn't straight. "Actually I think there are standards in Parliament. If you bring families or mothers into it you can expect to have a pretty firm bite-back from any politician." Corbyn has since responded to the PM's mother jibe. “If most of us are ashamed of shabby clothes & shoddy furniture let us be more ashamed of shabby ideas & shoddy philosophies" Einstein #pmqs — Jeremy Corbyn MP (@jeremycorbyn) February 24, 2016 And so has the rest of Twitter... Without the exchange on mums, half the press gallery would have thrown themselves over the rail during that dire #pmqs — Tim Shipman (@ShippersUnbound) February 24, 2016 When #PMQs descends into a series of 'Your mum' comments it shows all politicians up. It's school-ground antics that demeans @HouseofCommons — Tim Farron (@timfarron) February 24, 2016 Pretty sure what my mother would think of that #pmqs, but I'll spare you all. I think that was pretty much a win for nobody. — Gaby Hinsliff (@gabyhinsliff) February 24, 2016 . @asabenn We're not angry, we're just disappointed. — Mumsnet (@MumsnetTowers) February 24, 2016 My #PMQs review: The problem for Corbyn is the number of voters who agree with Cameron's mother https://t.co/IUssDPBkHo — George Eaton (@georgeeaton) February 24, 2016
