Online gaming firm bwin.party jumped on speculation that it could receive a licence to operate in New Jersey. "Now is the time for the state to move forward, leading the way for the nation, by becoming one of the first states to permit internet gaming," New Jersey's Governor Chris Christie was quoted as saying. Sector peer Playtech was also a high riser. Office provider Workspace was wanted after saying that demand for space remains strong with an increase in like-for-like rent roll in the quarter and the year to date as it continues with its programme of refurbishment and redevelopment. Insurer Catlin was firmly lower despite raising its dividend after reporting that annual profit before tax surged from $71m to $339m.
