Vladimir Putin may be "insane and an idiot" but he is "not Dr Evil", a major Tory donor born in the former Soviet Union has said.
Alexander Temerko, an energy tycoon who held roles in the Russian defence ministry in the 1990s, joined a number of people in questioning the Russian president's mental state after the invasion of Ukraine.
The Ukrainian-born British citizen said Mr Putin is behaving "like a collector of land" as he "tries to restore the Soviet Union".
