Tim Haines, who said two months ago that he would become chief executive of healthcare and biosciences firm Whatman, has decided to join Abingworth Management, the life sciences venture investment group, as a partner.

Bob Thian, chairman of Whatman, said: "Another opportunity has come Mr Haines' way which he believes offers him rewards beyond that which he would be able to earn with Whatman...We saw a number of excellent candidates in the original search process and are hopeful of being able to make an appointment in the relatively near future."
