May 28 (Reuters) - The chiefs of British Gas and its parentcompany, Centrica Plc , are close to stepping down aspart of a management shake-up at Britain's biggest energysupplier, Sky News reported on Wednesday.
Sky News said Chris Weston, who runs Centrica'sinternational downstream division, which includes British Gas,is in detailed talks about taking the top job at temporary powergroup Aggreko.
Centrica declined comment, while Aggreko could not bereached outside of normal business hours.
The news service reported that Weston's exit from Centricahas not yet been finalised, and sources close to the situationtold Sky that he had not yet formally landed the Aggreko job.
If Weston does secure the role, however, his departure islikely to be announced at roughly the same time as that of SamLaidlaw, Centrica's long-serving chief executive, sources toldSky News.
Sky reported that Centrica is in advanced negotiations toappoint a senior executive of BP Plc, Iain Conn, asLaidlaw's successor.
BP could not be reached outside of normal business hours.
Sources told Sky that announcements about one or more ofthese moves could be made as soon as this week, although thecomplexity of ongoing negotiations means that the appointments could yet be delayed or even fail to occur.
"There are a lot of moving parts around all of theseappointments," a source said. (Reporting by Aashika Jain in Bangalore)
