Richard Ratcliffe – the husband of Nazanin Zaghari-Ratcliffe – has ended his hunger strike after 21 days.
Mr Ratcliffe has been protesting out the Foreign Office in Westminster.
He wants the Government to do more to secure the release of his wife, being held in jail in Iran.
She has been locked up for the last five years.
The Foreign Office claims it is doing all it can to bring her back home.
Mrs Zaghari-Ratcliffe is accused of spying.
She has lost two appeals against the sentence.
