Warren Buffett has said he wants to invest more in the UK and other parts of Europe, despite uncertainty over the UK's future relationship with the EU.
The US investment guru said he would like his firm, Berkshire Hathaway, to be better known across the Atlantic.
"We're hoping for a deal in the UK and/or in Europe, no matter how Brexit comes out," the billionaire told his annual shareholders' meeting.
"I have the feeling it was a mistake," he said of the UK's vote to leave.
However, he added: "It doesn't destroy my appetite in the least for making a very large acquisition in the UK."
Mr Buffett, known as the "Sage of Omaha", is chairman and chief executive of Berkshire Hathaway, which owns dozens of US stocks.
The company reported first-quarter earnings of $21.7bn (£16.5bn) on Saturday, a marked improvement on last year's first-quarter loss of $1.1bn.
However, that does not reflect the performance of one of its more troublesome investments, the 26.7% stake in food giant Kraft Heinz, which has not yet filed its quarterly results with the US Securities and Exchange Commission.
