The senior detective leading the search for Ben Needham said his team is 'determined' to do all it can to solve the mystery around the disappearance.
Speaking on the Greek island of Kos, where his search team has been working for 19 days, Detective Inspector Jon Cousins said: "We need to find an answer for Ben's family and we are determined, each of us, to do whatever we can to do that."
He said there is 'no disappointment at all' at the search team not uncovering anything to help explain what happened to Ben when he vanished 25 years ago.
Ben was 21 months old when he disappeared while he was playing outside a farmhouse his grandfather was renovating.
His family always believed he was abducted but detectives are now working on the theory that he may have been buried by a digger clearing a building plot nearby.
A police search team has spent nearly three weeks excavating the land around the farmhouse, with DI Cousins revealing today that the work there was 'at a closing stage'.
His team is still searching a second site, where material moved by the digger on the day Ben vanished was dumped.
DI Cousins said he was still keeping an 'open mind' over what happened to Ben and he said there was enough Home Office funding available to support the search.
"There's no problem with funding," he said.
"We were very kindly given the funding from the Home Office. I have been in regular contact with the right people from the Home Office during this last three weeks. They are incredibly supportive of the work we are doing.
