The split came only 15 months after JWT was appointed following a pitch against Clemmow Hornby Inge and Delaney Lund Knox Warren & Partners. No ads aired during that time.
The account is separate to the Weight Watchers food account, which is held by Clemmow Hornby Inge.
A spokesperson for Weight Watchers said today: "We have a shortlist we are working through but there won't be an official pitch process."
It is thought that this short list will include Euro RSCG London. The appointment is expected in the next two months, and will be made by Melanie Stubbing, senior vice-president of Weight Watchers UK.
Brand Republic's sister magazine ±±¾©Èü³µpk10 reported that WPP Group's JWT had been briefed to create a campaign that would encourage people to join their local Weight Watchers meeting, but failed to crack it.
WPP-owned RMG Connect will continue to work on the direct marketing account for Weight Watchers.
