The chairman of Barclays Bank is expected to step down today as the row intensifies over the Libor rate-fixing scandal.
Reports said Marcus Agius was about to leave the embattled bank, as Business Secretary Vince Cable backed calls for a criminal investigation into bankers involved in the affair.
The Liberal Democrat Cabinet minister said the public could not understand why the perpetrators of “what looks like a conspiracy” were allowed to “just walk away”.
His intervention came as it emerged that taxpayer-backed RBS has sacked four staff over their alleged role in the Libor-fixing scandal.
The bank declined to comment on the matter but sources said the sackings were made at the end of last year.
