Bank says 18 other outlets will become ‘counter-free’ and further 36 will operate reduced hours

Santander is to close a fifth of its branches in the UK as part of an overhaul of its network, putting 750 jobs at risk.

The retail bank said it would shut 95 out of its 444 high street outlets, and reduce the services or hours at a further 50-plus branches, by June to “better serve the changing needs of customers”.
