Della Bovey, wife of video millionaire Grant, has been granted a ''quickie'' divorce on the grounds of his adultery with Miss Turner.

The presenter, who has also fronted Blue Peter and ITV's Wish You Were Here, was named as co-respondent in a petition heard by District Judge Berry at the Principal Registry of the Family Division in central London.

None of the parties attended the brief hearing.

The 38-year-old presenter announced recently that she is to leave the popular holiday programme to concentrate on her new life with Mr Bovey.

Failed reconciliation

Her workload was blamed for the breakdown of her marriage to former BBC Radio 1 disc-jockey, Peter Powell.

Miss Turner, and father-of-three Mr Bovey, also 38, have recently bought a house together in the village of Dunsfold, Surrey.

Mrs Bovey, 35, applied for the marriage to be ended in the wake of a failed reconciliation with her husband.

In a written court document she states: "In January 1998 the respondent (Mr Bovey) left me to go and live with the co-respondent (Miss Turner).

"In April 1998 he returned saying that he had finished with the co-respondent.

'Intolerable '

"By November 1998 I was suspicious that he was again involved with the co-respondent and in December 1998 he admitted that he was."

In the court documents Mrs Bovey, of Pulborough, West Sussex, who gives her occupation as "mother", was asked if she found it "intolerable" to live with the respondent.

She answered: "Yes."

On the custody arrangements for the children, Mrs Bovey says they should have ''staying contact'' with their father as long as they do not spend longer than three hours with Miss Turner at a time.

Mrs Bovey was also granted a costs order against Mr Bovey and Miss Turner.
