Cameron condemns the attack on Britain's embassy in Tehran as "appalling and disgraceful", says number one concern is the safety of staff.

We're not sure what he asked (distracted by his hair). Something about Regan and air traffic controllers.

"Another conservative prime minister for whom unemployment is a price worth paying".

Now Miliband's asking about the coalition's fiscal mandate - they have "failed" to balance the books because of higher borrowing costs.

"The truth is his plan has failed. He refuses to change course and he's making working families pay the price. At the very least we now know he'll never, ever be able to say again 'we're all in this together'."

Cameron accuses Ed Miliband being on the side of those who want to disrupt borders. He makes a trade-union related pun about Labour MPs shouting in the chamber "they're all shouting in Unison [geddit]"

Cameron: "We are being tested by these difficult economic times" but we will get through it.

He repeats that Ed M is weak, left-wing and irresponsible.

He's going down the 800k low paid workers route. This could be a good track - Ed gets a win when he goes down the detail route.

Now Ed is asking about unemployment.

Ed Miliband is now defending Labour's funding "better that than millions from Lord Ashcroft". Ouch.

"I don't want to see any strikes, I don't want to see schools close, I don't want to see problems at our borders", the PM says.

Despite the angry exchanges between the two leaders, the whole thing feels a bit subdued today - the action's elsewhere.

Ed Miliband says he won't demonise nurses who earn as much as Osborne spends on a skiing holiday.

"He is the one who went around saying he's privately delighted because they'd walked into his trap... It's not just public sector workers who are paying for the failure of his plan. It's private sector workers as well."

Now we're onto the Autumn statement and cuts to tax credits.

"He's been spoiling for this fight", says Ed. Isn't it true 800,000 low paid workers are facing an immediate tax rise?

Cameron, unsurprisingly, hits back and accuses Miliband of being in the pocket of the unions. "What he's just told the house is completely and utterly untrue". Ministers met with unions yesterday, and will do tomorrow, and Friday.

"Today, he now backs the strikes", says the PM. "Why? Because he's irresponsible, left wing and weak."

You may remember it:

He's asking about strikes - and the headteacher he praised in June for not striking, who has closed her school today.

"Why does the prime minister think so many decent, hard-working public sector workers... feel the government simply isn't listening."

Cameron defends himself, he says reforms to pensions are "essential" and he has a message for strikers: negotiations are still underway.

Asks about cuts to search-and-rescue helicopters. Cameron agrees to meet with him.

He asks about more support for enterprise zones in Wales. Cameron answers by talking about his Movember moustache and says "we are committed to providing enhanced capital allowances" in enterprise zones.

"Our thoughts should be with his family, his friends and his colleagues", says Cameron.

Number 10 say a "handful" of staff have joined the strike
