Heather Mills splits from publicist

Heather Mills's publicist has quit and branded the animal rights activist "impossible" to work with.

Michele Elyzabeth claimed that she was involved in a "heated argument" with Mills yesterday, which prompted the split.

"After working for Heather Mills for four years, I have decided to cease representing her," said Elyzabeth in a statement.

"Since her divorce has become final, in my opinion, Heather has become an impossible person."

The representative continued: "Yesterday, we engaged in a heated argument during which she called me 'stupid'. I reminded her that she was not 'God' and she answered, 'I will never ever talk to you again'.

"I have been very patient in my dealings with Heather, however, I cannot take any more. I have given her substantial unpaid time and attention."

She added: "On reflection and given the way I have been treated, I now have sympathy with much of what the British press have reported about her."
