Home Secretary Theresa May is expected to announce this afternoon whether police in London can use water cannon, shown above being used in Belfast recently.

Scotland Yard bought three second hand water cannon from German police last year at a cost of more than £200,000.

The move was endorsed by London Mayor Boris Johnson, even though they cannot be deployed without authorisation from the Home Office.

Mr Johnson has offered to face a blast of water himself, to show they are safe.

The DUP's Jim Shannon asks the foreign secretary what he is doing to address the issue of Iran's persecution of Christians. Philip Hammond responds that the talks were limited to nuclear issues but says "the only way you can have any influence over what people do is to engage with them". 

The foreign secretary says that the government will continue to target Iran's "appalling" human rights record.

How about the row within Labour about how to respond to George Osborne's Budget? Charlie Falconer says there is a difference of opinion on one issue - whether to limit child tax credits to two children. But he says the party is united on opposing the Budget for, as he puts it, discouraging work and placing a disproportionate burden on children. Conservative Amber Rudd says Lord Falconer is "trying to make sense of the utter confusion on the Labour front bench" on the issue and the SNP's Pete Wishart weighs in, highlighting a "series of contradictory statements" by Labour figures.

He says while we should hope for the best in these situations, "we must also prepare for the worst".

Former SNP leader Alex Salmond tells the House that Iran's President Rouhani is a "distinguished graduate" of Glasgow Caledonian University and urges the foreign secretary not to listen to "the prophets of doom" and to take this opportunity to welcome Iran back into the community of nations.

Philip Hammond says he was unaware of President Rouhani's connection with Glasgow Caledonian university and muses that perhaps the Iranian president did not need the many English translators he seemed to rely on during the negotiations.

The chair of the House of Common's Foreign Affairs Committee Crispin Blunt welcomes the deal and asks what plans the foreign secretary has to forge "effective and intelligent co-operation" between Saudi Arabia and Iran to form a common strategy to defeat the so-called Islamic State.

The foreign secretary thanks Dan Jarvis for his "constructive tone" and says that it was important that the deal was a win-win situation for all parties involved. Mr Hammond says that if the deal had been a triumph for Britain and the US but not for Iran, it would have been a "hollow victory" because it would eventually fall apart.

The foreign secretary also says that he hopes to reopen the British embassy in Iran before the end of the year.

Assessing the state of the parties as they near the summer recess, presenter Andrew Neil says the Conservatives are "on a high" while Labour is "mired in its leadership contest".

BBC deputy political editor James Landale says that is what the Tories are trying to exploit. They are putting pressure on Labour by way of the Budget and the proposed union reforms. "They're in relatively good fettle," he says.
