GAB Robins has lost its client services and sales director David Walker, who will leave the company through "mutual agreement".
The loss adjuster's UK chief executive, Kieran Rigby, said that Walker was now on "gardening leave for a few months" and finance director Ian Findlayson would take over his responsibilities.
Walker was instrumental in many of the company's business wins and was a key part of the AXA client relationship team.
"David had a long-term relationship with AXA but we have personnel working on all levels of this account," said Rigby.
Rigby said the company had made some significant new business deals, such as the subsidence contract for insurer Allianz Cornhill and the fraud investigation work for the Motor Insurers' Bureau. GAB Robins has also been retained on the Lloyds TSB personal lines account for all claims.
"In the coming two weeks we will present the business plan for 2007 and now the firm has been recapitalised
I hope we can progress quickly. The UK business makes up at least 25% of the GAB Robins Group revenue, helped by the favourable sterling rate against the US dollar," added Rigby.
He said that UK operations made "substantially more" than the rumoured £300m revenue up to 31 March 2006.
GAB Robins will cut its transcription services staff in its India operation from 70 to 50 staff.
It will also introduce a new IT system in early 2007, which will allow all claims files to be digitalised.
