Banking giant Barclays has increased its provisions to cover two mis-selling scandals by another £1 billion.
The banking giant will set aside a further £600 million for redress to cover mis-sold payment protection insurance, taking the current total to £2.6 billion.
And in the wake of the City watchdog's study into interest rate swap products sold to small and medium-sized businesses, Barclays will increase its provision in this area by £400 million to £850 million.
Last week, Barclays' new chief executive, Antony Jenkins, said he would waive his bonus for 2012 after a "very difficult" year for the scandal-hit bank.
The latest provisions were disclosed by the bank as Mr Jenkins and Barclays chairman Sir David Walker prepared to go before MPs and peers in the latest hearing of the Parliamentary Commission on Banking Standards.
Mr Jenkins is leading a campaign to repair the bank's image and overhaul its culture, which has been blamed for the wave of recent scandals, including Libor rate-fixing. He will present more details of the plan alongside the company's annual results next Tuesday.
But Mr Jenkins appears to be facing an uphill struggle, with reports last week suggesting it is the subject of yet another investigation as authorities look into allegations that it lent Qatar money to invest in the bank in 2008 as part of an emergency cash call to avoid a Government bailout.
The terms of the bank's fundraising at the height of the financial crisis are already being scrutinised by the Financial Services Authority (FSA) and the Serious Fraud Office.
The FSA last week announced that it had looked at 173 cases where so-called interest rate swaps had been sold to small firms as part of an industry-wide pilot study. It said a "significant" proportion were likely to result in redress being due to the customer.
Interest rate swaps are complicated derivatives which might have been sold as protection - or to act as a hedge - against a rise in interest rates without the customer fully grasping the downside risks. They were marketed as low-cost protection against rising interest rates, often as a condition of a business loan. But businesses as small as bed-and-breakfasts and takeaway shops were left with major bills after the financial crisis caused interest rates to slide.

Barclays ups mis-selling provision
Figures from charity Age UK show that 29% of those over 60 feel uncertain or negative about their current financial situation - with millions facing poverty and hardship.
Even though saving for retirement is not much fun, the message is therefore that having to rely on dwindling state benefits in retirement is even less so.
To avoid ending up in this situation, adviser Hargreaves Lansdown recommends saving a proportion of your salary equal to half your age at the time of starting a pension.
In other words, if you are 30 when you start a pension, you should put in 15% throughout your working life. If you start at 24, saving 12% of your salary a year should produce a similar return.
