Boothman, who has worked for Schroder Investment Management and was once chief executive of fund platform Cofunds, joined Jersey Finance in February 2009. He will leave in the New Year.
His departure is believed to be down to budget constraints and a decision being taken around where promotional resources can be deployed to best effect internationally.
Jersey said its representation in London would be continued through Martin De Forest-Brown, the States of Jersey’s director of international finance, who recently moved to the city on a permanent basis.
Geoff Cook, chief executive of Jersey Finance, will also be spending more time in London, as will Heather Bestwick, its technical director.
Cook said: “I would like to thank Clive for his excellent work over the past two years in developing Jersey’s profile in London.
"Our London office will remain open and active with support from our Jersey team, and all promotional activities will continue as planned.”
Boothman noted how through his and Jersey’s efforts the island "continues to be held in such high regard by the UK financial community".
In July, International Adviser, reported that Jersey Finance was planning to open offices in India and the Middle East by the first quarter of next year. It also has a Hong Kong office.
It was not known at the time of publication whether funding was still available for this expansion though clarification has been requested.
