Barclays reports a 13% rise in pre-tax profits to £4.2 billion in the first half of 2012, but reveals a potential £450m bill for mis-selling interest rate swaps.
Barclays is one of four banks which has agreed with the UK Financial Services Authority to compensate customers who were mis-sold interest rate hedging products.
The first half results make little reference to the recent Libor scandal, apart from an apology for recent events.
The bank does reveal, however, that four past and present senior staff, including group finance director Chris Lucas were investigated by UK regulators into fees they received under deals made in 2008.
