Insurer and asset manager Standard Life is likely to choose Dublin as the base for its European Union subsidiary after Britain leaves the bloc, its chairman said.
Standard Life already has an operation in Dublin and is unusual among British life insurers in having thousands of customers in the EU.
Financial services firms are looking to set up regulated subsidiaries in the EU in case they lose access to the bloc after Brexit.
"The most likely scenario - and the one we are now working towards - is using our Dublin-based operation to continue to support our European customers and clients," chairman Gerry Grimstone said in a speech given to shareholders at the firm's annual general meeting yesterday.
"We are now working through the regulatory matters and other arrangements we would need to put in place to facilitate this," he added.
Standard Life's choice of Dublin will be a boost for the city, which has lost out to high-profile insurers AIG and Lloyd's of London, which have picked Luxembourg and Brussels respectively.
Standard Life shareholders will vote next month on the firm's £11 billion merger with rival Scottish fund firm Aberdeen Asset Management.
Earlier this week, JP Morgan bought a building in Dublin's Docklands giving it the capacity to double its workforce here from 500 to 1,000.
