New data has shown that the number of complaints made to UK banks by their customers has risen considerably.

Complaints at embattled Barclays in the first half of this year were up 76% on the same period in 2011, with Royal Bank of Scotland receiving 128% more complaints.

The complaints include those for the mis-selling of payment protection insurance (PPI).

Banks are required by regulators to publish their figures twice a year.
