Tehran: Iran's Foreign Ministry summoned Britain's ambassador on Monday in protest at a decision by three British judges to uphold a ruling that the British government was wrong to ban an Iranian opposition group as a terrorist organisation.

The People's Mujahideen Organisation of Iran (PMOI) won a seven-year legal battle last Wednesday when three senior judges at Britain's Court of Appeal dismissed a government challenge to the earlier ruling.

Iran's Deputy Foreign Minister Mehdi Safari summoned British Ambassador Geoffrey Adams to voice the Iranian government's "strong protest", the Isna news agency said.
