Watch Tory MPs grimace as David Cameron's tortured McDonald's joke falls flat at PMQs

Ever heard the one about McDonalds and the party conference? You probably don't want to

Even David Cameron’s own MPs appear to be finding their leader’s jokes unfunny, after his latest gag was met with a rather dissatisfied response during today’s Prime Minister’s Questions.

After answering a question on education spending, Cameron decided to use recent claims that fast food restaurant McDonalds had been banned from Labour’s autumn conference to his advantage.

“When I read that they were going to ban McDonnell from their party conference I thought it was the first sensible decision they’ve made,” the Prime Minister started.

“But it turns out it wasn’t the job destroyer they wanted to keep away from their conference, it was one of Britain’s biggest employers.

As his backbenchers held their breath for the zinger’s close, out came the tortured end.

“No wonder Labour MPs are in despair, frankly I’m lovin’ it.”

The faces of those sat alongside Cameron sufficiently portrayed the joke’s poor reception, although the general murmurs of dissatisfaction surely confirmed any doubts the Prime Minister may have had over how funny he is.

Earlier in the session, the differing priorities of Cameron and Corbyn were clear for all to see in how they chose to acknowledge the Queen’s 90^th birthday celebrations.
