Junior stock exchange Plus Markets has parted company with two of its board members - including one of its former chief executives - as the venue continues to overhaul its strategy to better cope with difficult trading markets in the UK.

The London-based market today revealed that Simon Brickles, its vice-chairman and a former chief executive of the venue, had left his role earlier this week. Stephen Allcock, a non-executive director, also left his position. The group is looking to hire additional directors, but is not looking to fill the role of vice-chairman vacated by Brickles, according to a company spokesman.
