An informed source in the Iranian Foreign Ministry confirmed on Thursday reports of the reopening of UK embassy in Tehran.

The move marks a thawing of ties with Iran since it reached a nuclear deal with the United States, China, Russia, Germany, France and Britain.

"The foreign secretary (Philip Hammond) will travel to Iran to reopen our embassy there," a British diplomatic source told Reuters Thursday.

Hammond will travel to Iran this weekend for the formal opening of the embassy Sunday. He will take a small group of business leaders, including representatives from Royal Dutch Shell and other companies, with him on the trip, according to the source.

The British minister will have meetings with Iranian President Hasan Rouhani, Ali Akbar Velayati, who is a senior adviser to Iranian Supreme Leader Ayatollah Sayyed Ali Khamenei, and with Foreign Minister Mohammad Javad Zarif.

With the business delegation, Hammond will meet the Iranian ministers of industries and business, petroleum and transport.

Until a new ambassador is announced, the embassy will be led by Ajay Sharma, until now the non-resident chargé d'affaires.
