The wife of a jetskier who went missing six weeks ago off the coast of Bali yesterday welcomed an offer of help from the Foreign Office.

Jacqui Hoyland believes that her husband Jeremy could still be alive after drifting on to one of the hundreds of uninhabited islands in the region.

Mrs Hoyland and her brother-in-law Nicholas were in London yesterday making an appeal at the Foreign Office to get help in seeking mobile phone records to trace Mr Hoyland's position shortly after he went missing.

From these records, they hope to work out the direction in which he drifted.

Mrs Hoyland, from Penistone, near Barnsley, south Yorkshire, said that after a meeting with Foreign Office minister Bill Rammell she had gained fresh hope. She said: "Positive things have come out of our meeting with Mr Rammell.

"We have asked him to put pressure on the Indonesian authorities to come forward and help us with Jeremy's positions in the water.

"We hope this information will help us understand where he is.

"It has taken this long for someone with authority to get the ball rolling. These are golden hours."

Mr Hoyland, who is the father of Ellena, 13, and Georgia, 11, has more than 10 years' experience as a jetskier.

The 41-year-old was acting as the race director at the jetski sports event of the Asian Beach Games 2008.

He went missing on October 24, after setting off with four friends on borrowed jetskis for the Nusa Lembongan islet in the Indian Ocean.
