M&S Bank is closing all current accounts and linked monthly savings accounts in August, in a shock move which will also mean all 29 of its in-store bank branches will shut.
The bank says only a small percentage of its three million banking customers will be affected by the current account closures.
M&S Bank - half-owned by the retailer and HSBC - will continue to offer credit card, general insurance, savings and loan products.
The bank hasn't specified an exact date for the account closures, but customers will be given a formal 90 days' notice that their accounts are closing in May.
Here, Which? looks at why the bank is closing its doors and what the move means for its customers.
The business blamed its decision to close current accounts on the shift to online, particularly since the start of the pandemic, and said it will focus more on credit cards and store rewards.

You don't necessarily have to do anything, yet.
The M&S Current Account will continue to function for existing customers until the summer, but is now closed to new customers.

The 29 M&S Bank branches will close in early July, with all product servicing moving to online, mobile and telephone channels.

If you're an M&S Bank current account customer, this news may be disappointing for you, as you'll have to switch banks.
If you're already happy banking with M&S, you could consider moving to HSBC or First Direct, which are part of the same banking group as M&S.
HSBC and First Direct are offering welcome bonuses to M&S customers, provided their account was opened before January 2018.
HSBC is offering £125 to those who open its Advance account, pay in £1,750 a month or £10,500 over six months and switch two direct debits or standing orders.
First Direct will give you £100 if you switch and pay in £1,000 within three months.
