British bank Barclays on Thursday said its net profit jumped almost a quarter in the third quarter, helped by improved performance at its core UK and investment divisions alongside cost-cutting.

Profit after tax climbed 23 percent to nearly GBP1.6 billion ($2.1 billion) in the three months to the end of September compared with one year earlier, Barclays said in a statement.

"We continue to exercise cost discipline and remain well capitalised," said Barclays chief executive C. S. Venkatakrishnan.

Barclays in February outlined plans to slash GBP2 billion in costs over the coming years, having axed 5,000 jobs in 2023.

The bank remains on course to complete next week its takeover of the banking arm of British supermarket giant Tesco.

"The acquisition of Tesco Bank... forms part of our commitment to invest in the UK," Venkatakrishnan added Thursday.

Net profit at Barclays UK jumped 17 percent in the third quarter and by 12 percent at its investment banking division.

Shares in Barclays jumped 3.6 percent at the start of trading following the results update.

"Barclays is a multi-headed beast, and these numbers underline once more the strength of its diversified model," noted Richard Hunter, head of markets at trading group Interactive Investor.

Barclays is the second of Britain's four major banks to report in the current earnings season.

Lloyds Banking Group on Wednesday revealed a drop in net profits as interest rates fall around the world, adding that performance in the first nine months was impacted also by higher costs.
