The London Stock Exchange, which plans to develop its post-trade services, citing it as key opportunity for the future, has parted company with two senior experts in the field in the space of a month, it has emerged.

Bernie Kennedy, who was head of post-trade services at LSE-owned Turquoise, has left her post. She had held that role since the time of its launch in September 2008 and through its acquisition by the UK exchange earlier this year.
