Scandal-hit British bank Barclays says the head of its remuneration committee, Alison Carnwath, has resigned from the board with immediate effect for personal reasons.
"With regret I have concluded that I am no longer able to devote sufficient time to my role as a director of Barclays given my other commitments," Carnwath said in a statement issued by the company on Wednesday.
In April, more than one-fifth of Barclays shareholders voted against Carnwath's re-election as chair of the remuneration committee amid mounting anger over former CEO Bob Diamond's vast pay package.
Diamond resigned this month after the London-listed bank was fined STG290 million ($A442.58 million) for the attempted manipulation the Libor and Euribor interbank interest rates between 2005 and 2009.
American-born Diamond, who had become a symbol of excessive pay in Britain, also gave up bonuses worth STG20 million following his resignation, although he will still receive a final pay-off of about STG2 million.
The rate-rigging scandal prompted the resignations of Barclays chairman Marcus Agius and chief operating officer Jerry del Missier and sparked a fierce political debate over ethics in banking.
