Andersen Legal’s tied firm Dundas & Wilson has completed a $1bn (£700m) IT outsourcing deal between its regular client Bank of Scotland (BoS) and IBM in a landmark deal for the Scottish legal market.

The project, thought to be the largest of its type in Europe, will give IBM full management responsibility for providing IT to the Bank of Scotland Group from September for the next 10 years. About 500 BoS staff will join a 700-strong IBM workforce at a new IT centre in Sighthill, Edinburgh.
