London: Britain will reopen its embassy in Tehran led by Indian-origin diplomat Ajay Sharma during foreign secretary Philip Hammond's visit to Iran on Sunday, nearly four years after it was shut down due to a mob attack.
The British embassy will be staffed initially by a small number of diplomats led by Sharma, who has been the non- resident charge d'affaires since 2013.
A new British ambassador has been chosen but not yet announced.
The Iranian embassy in London will be reopened at the same time, as part of a rapid warming of relations between Iran and the west following the agreement reached on July 14 on Iranian nuclear programme, the Guradian reported.
Hammond would be the first British foreign secretary to visit Iran in nearly 12 years.
The embassy has been closed since 2011 after it was stormed by demonstrators protesting against Western sanctions imposed on Iran over its nuclear efforts.
The protesters climbed the walls of the embassy, burned the British flag and looted property from the living quarters.
Hammond will be accompanied on his visit by a handful of British business leaders as well as the Foreign Office political director, Sir Simon Gass, who represented Britain in the marathon talks leading up to the July nuclear agreement.
Before the storming of the British embassy in Tehran, Iran's parliament, the Majlis, voted to downgrade bilateral relations from ambassadorial to the rung below, the level of charge d'affaires.
The ties between the two countries have improved since the nuclear deal was made.
