The London Stock Exchange's chief operating officer and chief information officer has resigned and is set to join State Street, in what would be the second departure from the UK exchange group's senior executive team this year.

Antoine Shagoury, who joined the LSE as chief information officer in February 2010 to lead its efforts to become more nimble and tech-savvy at a time of stiff competition and falling trading volumes in the exchange sector, is set to join US financial services group State Street as its global chief information officer, according to two people familiar with the situation.
