Royal Bank of Scotland will today outline plans to invest £175 million in the institution's retail banking business north of the Border, with a further £450m to be spent on hardware for its Edinburgh information technology centre.

Chairman Sir Philip Hampton will tell shareholders at RBS's annual meeting at its Gogarburn headquarters, on the outskirts of the capital, that the investments will be made over the next three years.

However, Sir Philip is also expected to face discontent from shareholders over £607 million of staff bonuses awarded during a year when it lost £5.2 billion.

Payouts by the 81% state-owned bank have infuriated investors after a "chastening" 2012 when a £390 million settlement for Libor rate-fixing, another £1.1 billion of mis-selling provisions and a £175 million IT fiasco drove losses deeper from £1.2 billion in 2011.

But the bank will argue that it is on a stronger footing and should be ready for a return to the private sector by next year.

The £175m investment in the retail banking business will include branch refurbishment and new automated teller and deposit machines, with the aim of improving RBS's service to its customers.

This investment is expected to have a positive impact on jobs, although it is thought Sir Philip will not detail any figures regarding this.

The £450m investment in hardware at RBS's Edinburgh IT centre is aimed at improving the "resilience" of the bank's group-wide information technology.

RBS suffered a high-profile IT meltdown last summer, which locked customers out of their accounts.

Sir Philip will also update shareholders today on progress in rebuilding RBS, which was bailed out by the UK taxpayer after coming close to collapse in autumn 2008. In an interview last month, Ross McEwan, chief executive officer of RBS's UK retail banking division, revealed about 10% of RBS's UK branches were likely to be axed. He said RBS would consider any closure of the last bank in town on "individual merits".

RBS, which is about 81%-owned by the taxpayer, has around 300 branches in Scotland. It has around 2050 branches UK-wide, including 316 which it has been ordered to sell by the European Commission.

Mr McEwan has warned RBS's UK retail banking workforce will fall further from its current level of about 38,000, but he declined to estimate by how much.
