Richard Ratcliffe on sixth day of hunger strike at wife Nazanin's Iran imprisonment
Richard Ratcliffe has endured the sixth day of his hunger strike at his wife's imprisonment in Iran.
British-Iranian Nazanin Zaghari-Ratcliffe - who is also on hunger strike - was convicted of spying in Iran and jailed for five years in 2016.
She denies spying.
Mr Ratcliffe has been camping outside Iran's London embassy during his hunger strike.
The embassy has reportedly complained to the UK authorities about the protest.
The UK government has repeatedly called for Ms Zaghari-Ratcliffe's release, which the Iranian authorities have so far refused.
