Corbyn appeared nervous and unsettled as he rose to ask Cameron about the growth of low-paid jobs and zero-hours contracts in mining areas.
Cameron responded cordially to Corbyn's questions and both leaders seemed at pains to avoid discussing the elephant in the room that was today's publication of the Chilcot report into the war in Iraq, ahead of statements they will make later this afternoon.
However, the omission of Chilcot from Corbyn's questions was noted by public affairs and media commentators.
Yep, I also had that down as my main story of the day. https://t.co/Le6RaLk5Rr— Marie Le Conte (@youngvulgarian) July 6, 2016
Really valid questions about Govt infrastructure investment in the NE from Corbyn today...won't get any coverage thanks to Chilcot though...— (((Wil Barber))) (@wilbarber) July 6, 2016
It fell to a Conservative backbencher and then SNP leader Angus Robertson MP to raise the issue of the Chilcot report and ask if the UK was led into the war in Iraq on a false premise.
But Cameron refused to be drawn, saying that he would make a statement on Chilcot after PMQs.
Robertson also asked his second question about the failure of planning in the lead-up to Iraq, Libya and Syria but widened his question to include post-Brext planning.
But Cameron told him, in the context of war planning, that no manual existed that would effectively help a government of the future to plan for war.

There was a moment of levity when Cameron ribbed the Labour frontbenches with a quip that the Conservatives were in the midst of a leadership election, in reference to Corbyn clinging on to the leadership of his party.

Cameron drove the knife in deeper, asking how many of them wanted a leadership election on their side, to glum faces on the Labour benches opposite.

Then, in a strange encounter – perhaps for both men – Labour veteran Dennis Skinner MP, known as the 'Beast of Bolsover', made a direct appeal to Cameron to save Bolsover hospital, which is earmarked for closure.

Gesturing to the press gallery, Skinner wondered aloud whether a headline "Dodgy Dave assists The Beast to save hospital" might be the result of his enquiry.
Cameron ignored the dig and promised to look into the issue.
According to Brandwatch, there were 4,500 tweets around PMQs, with key topics including the Chilcot report and Dennis Skinner. Sentiment towards Cameron was 36 per cent positive and 64 per cent negative, while for Corbyn, 34 per cent of mentions were positive.
