Mr Patarkatsishvili said of his enemies: "I believe they want to kill me." Yuri Felshtinsky, a friend of Mr Patarkatsishvili, told the Standard the pair had met five days ago in London. The 52-year-old ex-KGB officer, who had known Mr Patarkatsishvili for 10 years, said he looked "fit and healthy" and quite happy despite losing in the Georgian elections last month. Mr Felshtinsky, who co-wrote a book, Blowing Up Russia, with Mr Litvinenko, said: "I saw him just on Friday and he was well and looked his usual self, which is cheery and happy. What happened is obviously very sad and although we have to wait and see exactly what took place yesterday, we can't ignore that he did have many enemies. The Russian government, the Russian secret service and the president of Georgia are just a few people who were on his list of enemies. Of course, knowing all this, he did fear for his life." Mr Patarkatsishvili recently hired the former Attorney General Lord Goldsmith, now a partner at the US firm Debevoise & Plimpton, to act for him. He met Lord Goldsmith at his offices at Tower 42 in the City yesterday before leaving to go to Mr Berezovsky's Mayfair office. He is then thought to have gone straight home at about 7pm. Although an opponent of Mr Putin, the most likely threat is believed to come from Georgia. He is accused there of plotting a coup after being caught on tape allegedly trying to organise the overthrow of president Mikhail Saakashvili.
