Emma Harvey will be replaced by FD Consumer Dynamics' Holly Clark, who is on secondment while Morgan Stanley decides whether it will replace Harvey.
In her new role at Homeserve, Harvey will form part of a rapidly expanding FTSE 250 firm.
Last month the Walsall-based company, which provides cover for home emergencies such as burst pipes, said its business has grown strongly with 1.6 million new policy sales in a 12-month period.
In a recent statement Homeserve said it also planned an agreement with an unnamed major household insurance firm.
The company, which employs more than 1,000 people at its call centre in Fulwood, Preston, has told shareholders it has signed an ‘outline agreement' with an unnamed firm about integrating its emergency repair service into policies. Homeserve and Harvey were unavailable for comment.
In 2001 Morgan Stanley brought FD's consumer arm in to boost its profile in the UK credit card market.
The appointment followed Morgan Stanley's plans to implement an integrated brand building communications strategy, including PR, sponsorship and advertising (PRWeek, 23 March 2001).
