UK financial markets remain volatile in the wake of the Brexit vote, with sterling plunging to a 31-year low against the dollar, and some share trading temporarily halted. Yields on 10-year government bonds sank below one per cent for the first time. Shares in airlines, housebuilders and banks were worst hit, with sharp falls causing a momentary halt in trading as automatic circuit breakers kicked in. The falls came after Chancellor George Osborne tried to calm the markets.In a statement before the markets opened, his first since the referendum result, the chancellor said the UK was ready to face the future from a position of strength. He also indicated there would be no immediate emergency Budget. But the upheaval on the financial markets continued.
