Iranian Parliamentary Speaker
Ali Larijani said Saturday that the parliament was renewing its demand to cut diplomatic relations with Britain.
"Britain has had a damaging role in Iran and these damaging moves and interferences should not remain unanswered," Larijani said, reported dpa.
A draft bill on cutting relations was to be debated in parliament he told Mehr news agency, though he did not say when.
Political tensions between Tehran and London were reignited after the disputed presidential election in 2009 when Britain supported popular protests against alleged electoral fraud.
The parliament has over the last year called on the foreign ministry to revise and even cut ties with the kingdom.
The row was given fresh impetus last month when the British ambassador to Tehran, Simon Gass, criticized Iran's human rights record and demanded the release of dissident, human rights activist and lawyer Nasrin Sotoudeh, on the embassy's official website.
The Iranian government has so far rejected parliament's demands, saying it instead preferred to downgrade some business cooperations.
