Boroujerdi who heads the national security and foreign policy commission of Majlis responded to a question about reducing ties with France since the French government has also taken initiatives for a freeze on the assets of the Central Bank of Iran.
"The issue of Britain is not simply limited to imposing sanction on the Central Bank of Iran. During the past three decades they have taken several damaging actions against the Iranian nation which putting a sanction on Iranian Central Bank comes only as the last act," he said.
Earlier on Saturday a majority of 179 Iranian lawmakers voted for expelling the British ambassador to Tehran, reducing the level of ties to charge d'affaires and limiting economic and cultural ties with the UK.
Referring to measures adopted by British embassy in Tehran after the disputed presidential election of June 2009, Boroujerdi added: "The British officials remember the role of their embassy in fomenting unrest in the country. They used the maximum potential of their TV (BBC Persian) and backed their friends in the region. So they have always taken negative positions against the Islamic Republic of Iran."
The lawmaker asserted that the British official took concrete steps in passing the UN Security Council's resolutions against Iran and pioneered such acts, "On the other hand, they have kept Iranian diplomat Mr. Nosratollah Tajik under house arrest for baseless allegations saying that they are to extradite him to the United States. Tajik is Iran's former Ambassador to Jordan and accusations again him are unfounded.
Arrested in 2006, Tajik was accused by British legal officials of allegedly trying to purchase night-vision goggles for the Islamic Republic's military forces from US mediators. He has been under house arrest for more than five years.
Referring to Majlis decision on reducing relation with Britain to the level of charge d'affaires, Boroujerdi said: "If the UK officials continue to play such game, we will make new decisions and that won't be the last step. We are the same lawmakers who earlier didn't bow to their wishes and prepared the ground for advancing our nuclear technology."
The latest report provided by the International Atomic Energy Agency's (IAEA) Board of Governors claimed Iran is seeking a nuclear weapon and led to a new round of economic sanctions being imposed by the West powers on Iran.
As a member of the IAEA and a signatory to the NPT, Tehran firmly rejects the allegation and stresses that its nuclear program is aimed at peaceful purposes including producing electricity.
