The outgoing chairman of Britain's biggest bank, HSBC, has called for an overhaul of financial crime detection as he sounded the alarm over the impact of Brexit and attempts to fragment global financial regulation.

Douglas Flint's warning came as HSBC reported a 5% rise in first half profits to $10.2bn (7.8bn) and announced a $2bn share buy-back - propelling the shares to a four year high.
