Royal Bank of Scotland Group is considering a sale of part of its Asia-Pacific business, as the British state-controlled lender continues its retreat to the UK.

RBS chief executive Ross McEwan has laid out a plan to ensure that 80% of the bank's assets are in the UK to cut risk and costs. On Sunday McEwan was in Singapore to discuss potential ideas for reducing RBS's footprint in the region, according to people familiar with the matter.
