Parts of the Dunfermline were sold to the Nationwide
Scottish MPs are to hold an inquiry into why the Dunfermline Building Society had to be rescued earlier this year.
The Scottish Affairs Committee will mount an investigation into the circumstances which led to the Nationwide buying parts of the society.
It will also look at the effect this has had on banking services.
Core parts of the Dunfermline were transferred to Nationwide Building Society in March.
The Treasury said it would take on about £1.5bn of commercial property lending and acquired mortgage debt under the deal.
The committee will take evidence from the Treasury, the Financial Services Authority, and the Bank of England.
MPs will also hear from the Dunfermline and Nationwide Building Societies themselves.
