Citigroup has made four hires to its London power and gas sales team, as the US investment bank continues to build its commodities arm while its peers scale back in the sector, Financial News has learnt.

Branko Pribicevic will join Citi in September from energy trading company Vitol to take up the role of head of European power and gas sales and origination, according to two people familiar with the situation. He has been at Vitol since 2009, prior to which he was at Morgan Stanley, according to his LinkedIn profile. Pribicevic did not respond to a LinkedIn request for comment.
