Prospects for Iran deal

Here's a look at what may await for the Iran nuclear deal in the other signatory countries:

Russia: If Russia signs and ratification is required, President Vladimir Putin's allies in parliament would be all but certain to provide it. Deputy Foreign Minister Sergei Ryabkov, Russia's main envoy at the Iran talks, said during previous negotiations that he did not think any final agreement would require parliamentary ratification.

China: Beijing has followed Moscow's lead during more than a decade of nuclear negotiations with Iran. The National People's Congress, which is subservient to the Communist leadership, is expected to quickly endorse any final deal if asked to do so.

Britain: The proposed deal has been welcomed in Britain and is not expected to meet any resistance should a parliamentary vote be required. Foreign Secretary Michael Fallon, a conservative, said the accord surpassed expectations from even 18 months ago. The opposition Labour Party, which could form the next government after the country's parliamentary election on May 7, has supported the negotiations and welcomed the agreement.

France: President Francois Hollande's Socialist government sought tough conditions in the negotiations, but was satisfied with the framework deal. The opposition conservative party, the UMP, has welcomed the deal, as have the leading far-left party and the Greens. Parliament would not need to vote on the accord.

Germany: Top figures in the broad, left-right coalition government — which controls four-fifths of parliamentary seats — have endorsed the deal. An accord is not expected to need parliamentary approval.
