The government must reveal what concessions have been made to Iran in the pursuit of a deal over its nuclear intentions, MPs have said.

The United States and five other nations are negotiating with Iran to curb its nuclear programme. Diplomats have until June 30 to conclude a deal.

Leading a Westminster Hall debate on Tuesday, Conservative MP Guto Bebb said “real questions” must be asked about what monitoring there would be of Iran in the event of a deal.

Middle East Minister Tobias Ellwood said it was important “to make it clear that we are working hard for the deal, but we need to make sure we reach the correct one. Without the correct deal, we have no deal”.

Former Defence Secretary Liam Fox said a nuclear Iran would encourage countries including Saudi Arabia, Egypt and Turkey to pursue their own programmes.

“The prospect of a nuclear arms race in one of the world’s most unstable regions, where the likelihood of the use of such weapons is probably greatest, should be of concern to us all. The stakes are enormous,” he said.

Mr Bebb, a Conservative Friends of Israel supporter who last year authored a report calling for a tougher stance on Iran’s nuclear ambitions, said the proposed agreement could leave Iran “at the threshold of a nuclear breakout” for the next 10 years.
Rehman Chishti highlighted Iran’s backing of Hamas. The Tory MP for Gillingham and Rainham added: “We cannot have a nuclear agreement with a state that is sponsoring and harbouring terrorism. It is a short-term fix for a long-term problem for the international community.”

Conservative Matthew Offord, Hendon MP, said nuclear weapons would boost the Iranian regime’s prestige “in the eyes of fundamentalist militant sympathisers such as Hezbollah in Lebanon and Hamas in Gaza”.
