TSB could disappear from UK high streets, after the bank's Spanish owner announced its sale to rival Santander.

The £2.65bn deal for the British bank still has to be agreed by current owner Sabadell's shareholders, but if it does go ahead, Santander is likely to integrate TSB into the Santander UK group, as reported by the BBC.

The takeover would create Britain's third biggest bank, based on share of personal current accounts.

While Santander said it hadn't made any decision on the future of the TSB name, the bank's chief executive Mike Regnier said: "We tend to use the Santander brand on the high street around the world".

A final decision on TSB's future isn't expected to be made until early next year. Before that, the deal needs the approval of both the Sabadell shareholders and the UK regulator.

TSB has 175 UK branches, including Cheltenham, Gloucester and Tewkesbury, and 5,000 staff. Santander has around 349 branches, but it is set to close 38 branches this month alone, saying more customers want to do their banking digitally.

Santander has admitted the takeover will lead to job cuts if it gets the go-ahead, as there will be duplication, particularly in back-office roles.

Marc Armengol, chief executive of TSB, which can trace its history back more than 200 years, said the deal would be "an excellent fit for our loyal customers".

TSB was once owned by Lloyds, which sold its remaining stake in the bank to Sabadell in 2015.
