The high-powered double act at the head of the UK's largest commercial radio group, GCap Media, is splitting up.

Ceo David Mansfield has quit, just five months after the £711 million ($1.36bn, €1.02bn) merger of his Capital group with GWR.

Ralph Bernard, executive chairman at GCap and formerly at GWR, will take over the ceo role.

Mansfield's departure is not altogether surprising, although the timing is somewhat abrupt. Shareholders raised concerns at the potentially confusing management structure of the merged company at the time of its union. Bernard insists, however, the decision was not made under shareholder duress.

He says, rather, it is the harmonious outcome of a strategy review, and Mansfield will remain at GCap in an advisory capacity until January.

Non-executive chairman Peter Cawdron claims two senior figures "made a lot of sense" following the merger deal, and that, "with the early integration nearing completion", the group had decided to change the set-up.

GCap came into existence against the background of a poor advertising market, which has made trading difficult for the enlarged company.
