Faysal Bank won a bid for Royal Bank of Scotland's Pakistan operations, a source said, allowing its Bahrain-based parent Ithmaar to expand its retail presence in the area.

Pakistan lender Faysal, which is 68 per cent owned by Ithmaar, beat Egyptian bank EFG-Hermes for the deal, the source said, but declined to give its value.

The purchase would nearly double Faysal's branch base and help grow its business in Pakistan, said the source.

'The deal is done,' the source said, adding that an announcement was expected next week.

Faysal Bank chief executive Naved Khan was not available for comment, while RBS declined to comment.

Pakistan's central bank said in March it had allowed Faysal Bank and EFG-Hermes to conduct due diligence on Royal Bank of Scotland's Pakistani operations, which comprise conventional and Islamic banking.

The planned sale of RBS Pakistan is part of a move by British government-controlled RBS to sell assets globally as it tries to exit from up to 36 countries and focus on its core domestic businesses.

'Faysal Bank has submitted a bid among other bidders to buy RBS Pakistan. This is in the final stages of being awarded to the winning bidder,' an Ithmaar spokesman said.

'The funding of this acquisition will be done completely internally and domestically arranged by Faysal Bank if this bid is awarded to Faysal Bank.'

MCB Bank said in January its bid for RBS's Pakistan operations had lapsed because it had failed to get regulatory approval.

MCB Bank had agreed in August to buy 99.37pc of RBS Pakistan for about $87 million.

RBS Pakistan had over 117 billion Pakistan rupees ($1.39bn) of assets as at March 31, 2008, about 5,000 employees and over 75 branches in 24 cities, according to its website.

Gulf Arab banks are eying expansion in Pakistan to tap the country's Islamic finance industry and to expand their retail footprint outside their limited home markets.

Ithmaar has just completed its transformation into a retail bank by integrating its fully-owned retail unit Shamil to improve its funding position.
