The mother of Ben Needham says the Prime Minister has refused to give her son's case the same financial backing as the McCann family.
Last month Kerry's MP Angela Smith asked David Cameron whether the Needhams could get similar funds as those given to the McCanns in the search for their daughter, Madeline.
In a written reply David Cameron says the National Crime Agency has supported South Yorkshire police, but made no mention of extra money for the Needham case. Kerry came into the Calendar studio and spoke to Christine Talbot.
The mother of Ben Needham says the Prime Minister has refused to give her son's case the same financial backing as the McCann family, despite a plea from her MP for assistance.
Last month Kerry's MP, Angela Smith, asked David Cameron whether the Needhams could get similar funds as those given to the McCann's in the search for their daughter.
The response has angered Kerry Needham, and Angela Smith says David Cameron could be accused of "favouring" one family over another. She now wants a national unit to investigate the cases of children missing abroad.
Calendar can also reveal tonight that a new dossier reveals EIGHT sightings of a blonde boy with the same Greek family. Mark Witty reports
The mother of Ben Needham has returned to Greece in the search for her son. Kerry Needham appeared on national Greek television this weekend, appealing for help in finding her son Ben who disappeared from Kos in 1991.
New information has come to light since the programme, which tries to find missing people. Kerry will be on Calendar tomorrow at 6pm to talk about the latest developments.
The mother of Ben Needham is tonight flying home to Sheffield, after an emotional return to the island of Kos where her son disappeared 21 years ago. Kerry has been on the island since the weekend with members of her family, hoping against hope
that nothing will be found in the excavation of the site from where Ben vanished in July 1991. The massive operation, involving UK Police and Greek volunteers, today went into its seventh day - with no sign of anything being discovered. Duncan Wood reports from Kos.
It's just been announced that Kerry Needham, Ben's mother will make a short statement after meeting Greek police in Kos town this lunchtime. She has spoken exclusively to Calendar after arriving on the island yesterday.
There is more heartache for the mother of Ben Needham as we can reveal a man in Greece is claiming to know the whereabouts of her son, but he wants half a million pounds up front before he will reveal what he knows.
Negotiations with the man have been ongoing for three weeks and the revelation has caused huge upset to Kerry Needham, as she feels her family is being held to ransom.
Although police on Kos say they are not aware of the development, Kerry's MP Angela Smith will be contacting the Foreign Office, asking for the Greek authorities to intervene. Mark Witty has this exclusive report.
