Ben Needham disappeared on 24th July 1991 when he was just 21 months old.
Ever since that fateful day her little boy vanished, Kerry Needham has campaigned tirelessly for police to continue investigating Ben’s disappearance.
And, earlier this year, South Yorkshire Police secured £700,000 of Home Office funding to fund an investigation into his disappearance.
In May, an appeal made on Greek TV led to more than 200 calls and emails being received by the force - and police have now confirmed that they are investigating several ‘very interesting’ new leads.
Detective Inspector Jon Cousins said: "[The Greek authorities] have given us every assistance that we require and that's allowed us to really progress this a lot further than where I thought we would be at this time.
"We're going to continue with our efforts looking in to everything that we have so far and, as we're going along, we're turning up new leads all the time that are very interesting to use.
"We're going to make sure that we pursue each and every one of those to try and find an answer for ourselves as well as for [Ben's mother] Kerry and the family."
Mr Cousins also confirmed that he has plans for another appeal to be broadcast on televisions on Kos, the Greek island which Ben was last seen on.
