President Mahmoud Ahmadinejad ordered the implantation of a parliamentary law requiring Tehran to reduce relationship with London, MNA reported.
On November 27, MPs approved a proposal calling for a reduction in the level of diplomatic and trade ties with Britain to a minimum level. The proposal was approved by a vote of 171 to 3, with 7 abstentions.
The proposal required Tehran to reduce its relationship with London to the level of charge d'affaires within two weeks.
After ratification by the Guardian Council on November 28, Majlis Speaker Ali Larijani announced the law to President Ahmadinejad.
According to Article One of the Civil Code of the Islamic Republic of Iran, the president is obliged to order the implementation of the law within five days after the announcement of Majlis speaker.
The Majlis ratified the proposal in response to the fact that Britain ordered all British financial institutions to stop doing business with their Iranian counterparts, including the Central Bank of Iran, on November 21.
The United States, Britain and Canada also imposed unilateral sanctions on Iran's energy and financial sectors over Tehran's nuclear program.
