Sir Gerald Howarth, Conservative MP for Aldershot, is cut off during his question by Speaker John Bercow who ticks off an MP for his "notably eccentric gesticulation", prompting laughter around the chamber.

Sir Gerald continues and asks the PM to send out a message of support to Christians around the world "who are suffering persecution" and to remind the public the country is fashioned by a Christian heritage and that we will not tolerate those who abuse our freedom to try to inflict their alien and violent fashions upon us, particularly in the name of Islam.".

David Cameron says the UK should do all it can to protect the rights of Christians to practice their faith across the globe. He says Britain is a Christian country and adds that it is a tolerant nation that is "better able to tolerate other faith groups".

The House is in quite a boisterous mood today. Perhaps it is excitement at the upcoming holidays. A Star-Wars related question from a Conservative backbencher is interrupted by the Speaker who has to call order. Responding a little later, the PM tried out a Star Wars gag, but it seems some in the chamber are unimpressed, with joke shouts of "Resign!".

UKIP MP Douglas Carswell challenges the prime minister over what he's seeking to achieve from his EU renegotiations. Mr Cameron, responding, says "I always find it hard to satisfy him," remarking that Mr Carswell left the Conservative Party after he promised the in/out referendum.

He says that it has thus come as no suprise that the UKIP MP is giving his boss "as hard a time as he used to give me" - but adds that nonetheless he wishes them a very happy Christmas.

"Britain is doing its moral duty in funding Syrian refugees and the refugee camps," David Cameron tells MPs. He says the UK has met its promise to resettle 1,000 Syrian refugees in the UK by Christmas, as part of plans to take in 20,000 by 2020

Gisela Stuart, Labour's Birmingham Edgbaston MP, calls for proper funding for the UK's museums and galleries. David Cameron says the British Museum is "a jewel in Britain's cultural crown". The Autumn Statement gave it a funding settlement which it welcomed, he adds.

Alison Thewliss, SNP MP, says the PM "reneged on a promise" not to restrict child benefit to two children. She asks him to drop the policy and "the rape clause". David Cameron says there's "no question" of someone who is raped and has a child of losing their benefits

As backbenchers' questioning of the prime minister continues, David Cameron takes an opportunity to pay tribute to Energy Secretary Amber Rudd who he says was one of the "key negotiators" at the Paris climate talks, and welcomes the deal agreed among world leaders.

Tulip Siddiq, a Labour MP, raises Donald Trump's call for a ban on Muslims entering the US. She asks the PM if he agrees the US presidential hopeful should be banned from coming here.

David Cameron says he's proud to represent a country that is one of the "most successful multi-racial, multi-faith and multi-ethnic countries" in the world.

He agrees it's right to exclude people who are going to "radicalise or encourage extremism" but he doesn't endorse banning Mr Trump. He tells MPs if the US presidential hopeful  came here "it would unite us all against him".
