AGGREKO has seen its shares rise one per cent after confirming its incoming chief executive Chris Weston will take on the role early next year.

Mr Weston, who has been serving out his notice period at British Gas owner Centrica, was announced as the successor to Rupert Soames in May this year.

But there had been uncertainty over the eventual start date at the temporary power supplier.

Ken Hanna stepped in to be executive chairman when Angus Cockburn, the long-serving finance director who worked alongside Mr Soames, left his role as interim chief executive at the end of September.

Mr Cockburn moved to join Mr Soames in his turnaround of outsourcing firm Serco.

Yesterday Aggreko, which has its headquarters in Glasgow, said Mr Hanna will revert back to his non- executive chairman role when Mr Weston arrives on January 2.

Mr Weston had been with Centrica since 2001 and prior to that had worked in the telecoms industry with the likes of Cable & Wireless and One Tel.

The certainty over Mr Weston's start date cheered investors with the share price closing the day up 15p to 1522p.

Aggreko is scheduled to give an update on its third quarter trading this month.
