A growing number of people have doubts about the conviction of Scott Watson for the murders of Olivia Hope and Ben Smart in 1998, according to a new poll.

Watson is serving a life sentence in prison, despite continuing campaigns by supporters who question his guilt.
The survey found just 23 percent of those polled now believe Watson is guilty, down from 59 percent in 2002. The margin of error was plus or minus 3.6 percent.
The research was commissioned by a supporter of Watson, Mike Kalaugher.
He hoped the Justice Minister would take the growing public concern about Watson's convictions into account.
"It's time really for the minister to get somebody to just have a good, objective look at it, and just say 'today, what's the basis of the case?'," he said.
Olivia Hope and Ben Smart's bodies have never been found.
