Strax UK managing director Barry Colman has left "to pursue personal interests".
The UK division of the US accessories distributor will be overseen by Ingvi Tomasson. The UK business, led by UK head of sales Mark Pearce and UK finance director Nick Pratt, is expected to be restructured.
Other regional Strax businesses operate as marketing offices, without an MD role.
Strax managing director for EMEA Birgir Birgisson said: "Barry’s contract was until the end of June. The UK is an important market and the plan is to carry on with customer acquisition as we have been doing this year."
Colman joined Strax two years ago with its acquisition of German distributor ‘more…’, with which Colman had worked as managing director for four years previously.
