G7 warns of 'adverse implications' over Brexit

Tokyo - Finance ministers and top central bankers from the Group of Seven warned that Britain's vote to quit the European Union would have "adverse implications" as the pound dived to three decade lows and equity markets flew into a tailspin.

"We recognise that excessive volatility and disorderly movements in exchange rates can have adverse implications for economic and financial stability," the club of rich nations said in a statement.

"G7 central banks have taken steps to ensure adequate liquidity and to support the functioning of markets.

"We stand ready to use the established liquidity instruments to that end."
