European commission officials who worked for Lord Mandelson, the business secretary, issued a misleading statement about the history of his relationship with Oleg Deripaska, the Russian billionaire, the Guardian has established.
Mandelson's officials in Brussels, where he served as trade commissioner before returning to a role in the government earlier this month, said the two men met "at a few social gatherings in 2006 and 2007", but had never discussed aluminium, the main source of Deripaska's wealth.
However, Mandelson and Deripaska were seen together at a Moscow restaurant in October 2004, after he had been appointed trade commissioner, but before he formally took up the post. A journalist spoke to both men and their companion, German Gref, who was then the Russian economics minister, and the event is also described in the blog of Benjamin Wegg-Prosser, Mandelson's former adviser and close friend.
The statement by the European officials is understood to be based on information provided by Mandelson himself. It is unclear why the business secretary has not corrected it to reflect the earlier meetings. The disclosure that the two men had met earlier is likely to fuel Conservative demands for an investigation into the relationship between Mandelson and the Russian oligarch.
