"This is all very strange", responds Jeremy Corbyn - accusing the PM of changing his mind on the policy. He says the PM vowed not to cut child tax credits during the general election campaign, so why should he be believed? David Cameron says the government pledged to cut welfare by £12bn "and we are keeping our promises to deliver a stronger economy". He notes deputy Labour leader Tom Watson's absence in yesterday's tax credits vote, which he brands "strange".

Continuing with his strategy of asking questions put to him by the public, Jeremy Corbyn says cutting tax credits restricts the life opportunities of self-employed people.

David Cameron says that people on the lowest incomes will continue to receive child tax credit at  £2,730. Income tax allowances are also being cut and there's a self-employed allowance, he argues. He adds the economy is growing and wages are rising.

Labour leader Jeremy Corbyn leads his questioning of the PM on tax credits - seeking to highlight Tory divisions over the policy. David Cameron defends the policy, saying it is part of a package that includes a higher living wage and tax reductions. He says he was "delighted" the measure was approved by MPs in yesterday's vote.

It's time now for this week's Prime Minister's Questions. Susan Elan Jones, Labour MP for Clwyd South, has the first question to David Cameron - and asks about Sunday trading laws.

The PM says there's a strong case for change - but says local authorities should be allowed to decide whether to extend Sunday trading hours. "I think it's time to modernise our approach to give families more choice" and to create more jobs, he argues.

BBC political editor Laura Kuenssberg thinks Jeremy Corbyn will raise job losses in the UK steel industry today, particularly topical she says given the "awkward timing" of the Chinese president's state visit to the UK.

Security minister John Hayes is asked about reports in The Times that British spies will be able to hack into smartphones and computers under new laws to be put forward by the government.

He says security services have to make a “reasonable case” to require a warrant. The bill “clarifies that” and builds in greater transparency and oversight, he adds. Mr Hayes says a warrant is currently granted by the home secretary but the government is considering suggestions for judicial oversight.

The Investigatory Powers Bill is expected to be published next month.

Shadow minister Chris Bryant draws comparisons between the tax credits row and Gordon Brown's 10p tax rate fiasco. He goes on to crticises the plans to cut tax credits and says he thinks the government will be punished for it at next year's local council and mayoral elections.

But security minister John Hayes says tax credits were introduced to help those in need, not to subsidise low pay which is what he says is the case now. Employers need to "step up to the mark" and pay a proper wage, he adds.

Sources from the Department for Work and Pensions  say Justin Tomlinson, minister for disabled people, is staying in his job and has the confidence of secretary of state Iain Duncan Smith and the prime minister. Mr Tomlinson has apologised and accepted he broke the rules.

Justin Tomlinson, the Conservative MP for North Swindon, is in trouble after breaking parliamentary rules.

Mr Tomlinson, who used to sit on the Public Accounts Committee, leaked a draft committee report on payday lenders to a Wonga employee in 2013.

An official investigation has ruled the actions of the MP, who is now a government minister, were a substantial interference with the work of the committee, and a further disciplinary procedure is underway.

He has apologised unreservedly, saying it was due to his relative inexperience.

He says he was motivated by his wish to take effective action against payday lenders.
