Barclays under its new chief executive Jess Staley has reported an improved business performance, helping drive the shares up more than five per cent.

Reporting 24 hours after Lloyds signalled a drop in profits and fired the gun on 3000 job cuts and 200 new branch closures, beset by uncertainties over the UK economy where it is now solely focused, Barclays benefited from becoming a ‘transatlantic’ bank focused on the US as well as UK.

Mr Staley in March set out a strategy to simplify the bank's structure and seek higher shareholder returns through the sale of the bulk of its Africa business and other assets. The bank said profits from its core businesses, including consumer and commercial lending, credit cards and investment banking, rose 19 percent to £2.4 billion pounds in the first half.

Group pre-tax profit fell 21 percent to £2bn, largely due to a loss of £1.9bn on the non-core assets which the bank has recommitted to offload, despite prospects of a possible economic downturn following the vote to quit the European Union.

Mr Staley told analysts: "Our assessment is that the Brexit vote in the UK will have no effect on our ability to run down non-core at an accelerated pace and we therefore remain confident in reiterating our goal of closing non-core in 2017.”

The bank booked a £372m impairment on the French retail banking business it is in talks to sell to AnaCap Financial Partners.

Other assets earmarked for sale include its Barclaycard consumer payments business in Spain and Portugal as well as almost all of its stake in its Africa unit. It has already sold its Asia wealth operations and Italian banking business.
