Co-op to create 3,000 new jobs
As part of the expansion, the group plans to open five regional hubs across England in the next five years, including the North West, North East, Midlands, South East and South West.
Positions will be mainly filled by legal staff, but other roles may become available in IT, HR and legal support.
The Co-operative also plans to extend its legal services across all 330 high street branches of the Co-operative Bank and Britannia Building Society.
Peter Marks, Group Chief Executive of the Co-operative, says: "We intend to be totally consumer focused and will help customers navigate the legal world so that they are much more comfortable with the experience and outcomes.
"Our ambition is to provide a service that will stop people feeling daunted by the prospect of having to work with a solicitor."
