Santander is set to acquire TSB for £2.65 billion, potentially leading to job losses and branch closures in the combined entity.
The acquisition is a strategic move for Santander, making it the third largest UK bank in terms of personal current account deposits if approved by Sabadell's shareholders.
The deal could result in the disappearance of the TSB brand, impacting its 5 million customers, 175 branches, and 5,000 staff.
TSB's history includes being hived off from Lloyds in 2013, experiencing an IT meltdown in 2018, and now facing its third major ownership change in 12 years.
