Didn't Trisha Goddard have some drama with Dianne Nelmes, another ITV daytime executive, hence why she defected to C5?

Trisha wanted her show to be produced by Townhouse Television, a company formed by her and former Anglia Television executive Malcolm Allsop (who had hired her to take over from Vanessa Feltz), therefore giving her a bit creative control over it. 

Nelmes refused to entertain the idea, so Trisha went to C5 when they were able to give her the creative control.

Sounds similar to the reason Paul O'Grady defected to Channel 4.
