Former Cabinet Secretary Lord O'Donnell has emerged as one of the leading frontrunners to take the role of Barclays chairman.
According to the Telegraph, senior figures at the bank have tipped Lord O'Donnell to become Barclays' new chairman, following the departure of Marcus Agius (pictured).
O'Donnell has also been linked to several high profile roles in the past, including the governor of the Bank of England.
Meanwhile, Bill Winters, former co-chief executive of JP Morgan's banking division, is favoured to replace chief executive Bob Diamond.
Winters was previously a member of the Independent Commission on Banking, set up by Chancellor George Osborne, which suggested ring-fencing the retail banking operations of major universal banks like Barclays.
It is still unconfirmed whether the two men have been offered the roles, or if they would consider taking them.
Both Agius and Diamond left the bank following the LIBOR-rigging scandal that has dominated headlines over recent weeks. Barclays was hit with £290m of fines by the FSA and the US Commodities Futures Trading Commission (CFTC) for deliberately fixing the LIBOR rate.
Speculation over Agius and Diamond's replacements comes as Sir Michael Rake, Barclays' deputy chairman confirmed he would not become chairman. Rake is chairman of low cost airline easyJet.
Rich Ricci, head of Barclays' investment bank, has also denied reports of being in the running to replace Diamond.
