Oriel Securities, the mid-sized UK stockbroker, has carried out a top-level reshuffle in changes that have led to the departure of its head of debt advisory and the appointment of a new head of equity capital markets.

Michael Berry, who joined the firm in September last year when his Versatus debt advisory business was snapped up by Oriel, left the broker at the end of March, according to a source close to the situation, who added that he had done so to "pursue other opportunities".
