Staffordshire-based firm Knight & Sons is losing two partners, bringing the number of partners who have quit to five in nine months.
Nick Davenport, senior partner in the corporate finance department at Knight & Sons' two-year-old Manchester office, has left after 26 years to join local practice Turner Parkinson.
Stephen Belshaw, who headed the litigation department, which specialises in construction, at the firm's Newcastle-Under-Lyme's head office leaves at the end of August to join Birmingham-based Lee Crowder as a litigation partner.
The firm had 19 partners at the end of last year. It is now down to 14.
Davenport says: "There was a lack of support for the Manchester office. The attitude of some partners was 'out of sight and out of mind'.
"When the office was first set up there were a lot of opportunities to get work and we were very successful."
Knight & Sons joint managing partner Derek Miller disputes claims that the firm neglected to provide resources for the Manchester offices.
He says following a restructure last year he is looking to drive up profits.
Manchester firm James Chapman & Co is also losing a partner to Turner Parkinson. Nick Marshall, a partner in company and commercial will join as a partner in corporate finance.
