Turquoise, the equity trading venue owned by the London Stock Exchange and a consortium of investment banks, has reappointed the former head of rival initiative the Plato Partnership to its board.

Stephen McGoldrick, a director for market structure at Deutsche Bank, rejoined the board of Turquoise in January, according to company filings. He had stepped down from the role in December 2014 due to his involvement with Turquiose's competitor Plato, which is owned by a group of banks and buyside firms and plans to launch a block trading venue later this year.
