The group, which is 25% owned by the taxpayer, said it "substantially improved" its financial performance in the six months to June 30, with profits excluding the PPI charge up 32% to £3.8 billion.
The overall profit of £863 million came despite a hit of £1.1 billion to cover legacy issues, including its £217 million fine this week for rate-rigging which included ripping off the Bank of England over its financial life-support scheme.
The group's £600 million increase in its provision for expected PPI costs in the second quarter brought the running total to £10.4 billion, of which more than £2 billion relates to anticipated administrative costs.
