The former chief financial officer of Chi-X Global has joined the board of Icap's new securities exchange, as the interdealer broker continues its revamp of the bourse it bought from Plus Markets this summer for £500,000.

Richard Dellabarca, who was chief financial officer of equity platform operator Chi-X Global until August, has joined the board of Icap Securities and Derivatives Exchange as a non-executive director, according to documents filed with Companies House last week.
