LONDON (IRNA) -- The British government said Saturday that it was considering Iran's response to a letter sent by the five permanent members of the UN Security Council plus Germany over the country's civilian nuclear program.

A Foreign Office spokesman confirmed that Britain received the response on Friday evening, which secretary of Iran's Supreme National Security Council Saeed Jalili described as ""constructive and creative"" and focused ""on common ground.""
""We are now consulting with our E3 plus 3 partners,"" the spokesman told IRNA. The response was delivered to the Foreign Office by Iranian Ambassador to London Rasoul Movahedian on Friday evening.
It came after the response was also delivered to the office of European Union Foreign Policy Chief Javier Solana in Brussels. It was also understood that copies were being sent to the capitals of all the respective countries.
Western diplomats declined to disclose details but spokeswoman for Solana, Cristina Gallach, was reported to have described a phone conversation between Jalili and Solana as ""constructive"" and that ""all the noises are positive.""
The British Foreign Office spokesman said that he had not seen Iran's reply himself but understood that it was by way of a letter signed by Foreign Minister Manucher Mottaki.
The response comes after the foreign ministers of the 5+1 sent a letter to Iran, offering to open negotiations to resolve the dispute over the country's civilian nuclear program. It was delivered by Solana in Tehran last month with a new package of incentives.
