John Fredriksen, UK's ninth-richest billionaire, has put his 300-year-old Georgian manor in London on sale after relocating to the UAE. The Norwegian-born's mansion, The Old Rectory, is one of Britain's most-expensive houses worth £250 million (over ₹2,900 crore) and is UK's third-largest private residence after Buckingham Palace and Witanhurst. "Britain has gone to hell, like Norway," he said.
