Law firm Mills & Reeve has swooped for Manchester-based legal company George Davies in a deal that will bolster its presence in the north.

The acquisition for an undisclosed fee will expand Mills & Reeve's Manchester team to 16 partners and 89 staff – bringing the firm's total operation to 112 partners and 870 staff across six offices in Norwich, Birmingham, Cambridge, Leeds, London and Manchester.

The deal will see all George Davies offices rebranded as Mills and Reeve, with staff at the bought-out firm transferring on June 1.

It brings Mills and Reeve's revenues to £77m – an increase on its 2011/12 turnover of £69.4m.

Guy Hinchley, the firm's managing partner, said: 'This merger will enable us to grow our presence in the North substantially and to progress our strategy of providing a full range of legal services to clients in our key sectors.

'We are very excited about the potential that our increased scale gives us and the further career opportunities that it creates for the talented lawyers and business support professionals in our enlarged firm.'

Mark Hovell, George Davies managing partner, said: 'As a well established, profitable, Manchester firm we have had regular approaches from firms... We chose to merge with Mills & Reeve as we have a lot of synergy with them and their culture closely reflects ours.'
