Litvinenko met with two former agents early on the day he fell ill – Dmitry Kovtun and Andrey Lugovoy. Though both denied any wrongdoing, a leaked US diplomatic cable revealed that Kovtun had left polonium traces in the house and car he had used in Hamburg. The men also introduced Litvinenko to a tall, thin man of central Asian appearance called 'Vladislav Sokolenko' who Lugovoy said was a business partner. Lugovoy is also a former bodyguard of Russian ex-Acting Prime minister Yegor Gaidar (who also suffered from a mysterious illness in November 2006). Later, Litvinenko had lunch at Itsu, a sushi restaurant in Piccadilly in London, with an Italian acquaintance and nuclear waste expert, Mario Scaramella, to whom he made the allegations regarding Italy's Prime Minister Romano Prodi. Scaramella, attached to the Mitrokhin Commission investigating KGB penetration of Italian politics, claimed to have information on the assassination of Anna Politkovskaya, 48, a journalist who was killed at her Moscow apartment building in October 2006.
