The group, which is 25% owned by the taxpayer, said it plans to "digitise" the bank, adding that it wants to simplify the business and be more efficient.

The Taxpayer-backed Lloyds Banking Group is to cut 9,000 jobs over three years and shut 150 branches, it announced.
At least 9,000 jobs will be axed at Lloyds Banking Group over the next three years along with an unknown number of branch closures, Reuters has reported, citing sources.
The cuts would amount to 10 per cent of Lloyds' workforce and follow some 30,000 job axings by the company since the financial crisis of 2007 to 2009.
Reuters reported the job cuts will be announced by Chief Executive Antonio Horta-Osorio in a three-year strategy review next week.
The report said the increase of online transactions and automated bureaucracy will lead to the closure of some branches.

Lloyds Banking Group's sale of a 35% stake in TSB will net the taxpayer-backed bank £455m.
The Initial Public Offering (IPO) will see 30% of the stock allocated to around 60,000 ordinary retail ivestors as TSB returns to the market as an independent company for the first time since its 1995 merger with Lloyds.
TSB is currently the seventh biggest UK retail bank with 631 branches and the IPO valued its shares at 260p each, giving the company an overall value of £1.3bn.
Lloyds Bank's sale of 35% of TSB shares is an "important step" for the company, according to chief executive Antonio Horta-Osorio.
The sale of the shares follows a 2009 decision by the European Commission to force the sell-off of TSB in order to increase competition in the UK banking sector.
Lloyds will have to sell off the remainder of its shares in TSB by the end of next year as part of the ruling.
Mr Horta-Osorio welcomed the move, saying: "The successful initial public offering of TSB is an important further step for Lloyds Banking Group as we act to meet our commitments to the European Commission."
Lloyds Bank has increased the number of shares it is selling in TSB as a result of strong demand from investors.
The bank, a quarter of which is owned by the taxpayer, had initially decided to sell a 25% stake in TSB but has now upped the proportion to 35%.
The shares have been priced at 260p each, giving TSB a market value of £1.3bn.
TSB bank is to be valued at between £1.1 billion and £1.45 billion when Lloyds Banking Group sells a 25% stake in the bank towards the end of June.
