Iran and Britain: a tense relationship
The Iranian government has often accused the West of interfering in its politics.
The United States has been cast as the Great Satan and there has been no shortage of anti-Israeli rhetoric coming from Iran's leaders.
However, in recent days, the authorities have been focussing particular attention on Britain.
Last Friday, Iran's supreme leader Ayatollah Khamenei called Britain the most "evil" of the "hungry wolves in ambush" on Iran.
The Iranian government has expelled two British diplomats and the British have responded by expelling two Iranians.
