A British couple detained in Iran on espionage charges have requested an urgent meeting with the Foreign Secretary after the pair were 'suddenly whisked' to a courtroom.

Lindsay and Craig Foreman, both 52, were arrested in Kerman, southern Iran, on January 3, as they embarked on a motorcycle trip around the world to Australia.

The couple, of east Sussex, had intended to travel from Armenia to Pakistan via Iran when they were intercepted by authorities and later charged with espionage.

Their arrests came after ignoring pleas from friends, family and the Foreign Office not to visit the nation before attempting to journey across the entire length of the country.

Foreign Office guidance advises against all travel to Iran, adding that travellers could be arrested just for 'having a British passport or connections to the UK'.
