Outside the Iranian embassy Richard Ratcliffe’s hunger strike continues into a seventh day.
With the aim of forcing the release of wife Nazanin - who is also on hunger strike inside Iran's Evin prison - the strike has seen support from a number of MPs including deputy leader of the Labour Party Tom Watson.
The metal barriers erected by the Iranians to mask the embassy's entrance have now been decorated with messages from supporters.
Mr Watson wrote on Twitter: "Today I met Richard Ratcliffe, husband of @freeNazanin, during his hunger strike at the Iranian Embassy.
"His family is trapped in a terrifying geo-political game.
"I urge the Iranian govt, to assist the de-escalation of military tension, and release Nazanin as an act of humanity."
things develop here."
Meanwhile the Iranian Ambassador to the UK Hamid Baedinejad claimed Richard's protest had flouted the Vienna Convention which protects the right to conduct consular activities, and suggested suggested Nazanin Zaghari-Ratcliffe could apply for clemency, adding the Iranian authorities were ready to help.
He said: "There are certain provisions for clemency but there are certain requirements and if the requirements would be met, certainly there is a solution and we are ready to help."
When the suggestion was put to Richard outside the embassy, he said he was not keen to do anything that could throw his wife's innocence into question.
"We'll see," he said. "Candidly I'm not sure I want to give away the idea that she's innocent. But we'll see how things develop here."
Tomorrow (Sat) supporters are invited to visit Richard and the embassy where stones will be painted as a gesture of solidarity with Nazanin at midday.
Nazanin has now been kept away from her Fortune Green home for more than 1,000 days.
