Calls for Barclays boss to quit

Pressure mounted for Barclays Plc chief executive Bob Diamond to quit after Britain’s third-biggest bank sacrificed its chairman over an interest rate rigging scandal that has dealt “a devastating blow” to its reputation.

Chairman Marcus Agius, who said “the buck stops with me”, is the first major scalp from a scandal that cost Barclays a record fine and is likely to involve more banks and embarrass financial regulators.

Mr Diamond was running Barclays’ investment banking arm when the rate manipulation took place.
