Nazanin Zaghari-Ratcliffe, a dual British-Iranian citizen, is serving a five-year sentence after being convicted of plotting to overthrow Iran's clerical establishment.
FOREIGN Secretary Boris Johnson has heeded calls to condemn Iran's detention of the wife of a Farnham man, and offered to visit her in prison.
The charges have been repeatedly denied by her family and her employer, the Thomson Reuters Foundation.
Zaghari-Ratcliffe's fate become a major political issue in Britain after Johnson said on November 1 that she had been teaching people journalism before her arrest in April 2016, contradicting statements from her employer.
Johnson later said his remarks could have been clearer and there was no doubt she had been on holiday, although opposition Labour Party leader Jeremy Corbyn said he should resign.
Iran's state-controlled television had seized on his remarks and claimed it was an implicit admission of guilt.
"I reject any suggestion that she was there in a professional capacity", he added.
"I apologize for the distress and anguish caused to Ms. Zaghari-Ratcliffe and her family".
The conservative representative for Tonbridge and Malling spoke after Mr Johnson restated the Government's plea that Iranian authorities release Mrs Zaghari-Ratcliffe on humanitarian grounds. "I don't know whether that will be possible but we will see what we can do", Johnson said.
The Foreign Office, however, issued a statement saying that in response to the outcry over Johnson's original remarks he discussed the matter with Iran's Foreign Minister, "to raise again his serious concerns about the case and ensure his remarks are not misrepresented".
He said that he would seek to meet Zaghari-Ratcliffe during his planned trip.
