UK police get extra funds to find Maddie

The parents of Madeleine McCann have been given new hope after police were granted an extra GBP154,000 ($A264,000) to continue the investigation into her disappearance.

More than GBP11 million has been spent on the probe to find the missing girl, who vanished from the family's holiday apartment in Praia da Luz in Portugal in May 2007, aged three.

Funding for the investigation, known as Operation Grange, had been agreed up until the end of September.

But the extra funds were granted by the Home Office following an application by the Metropolitan Police.

It is understood the number of officers working on the investigation will remain the same.

Madeleine's parents Kate and Gerry McCann have vowed never to give up hope of finding their daughter.

Since 2011, the Met Police have been assisting with the search for clues about what happened to Madeleine, with officers visiting the holiday resort in 2014.

In March, the Home Office granted officers GBP85,000 to cover "operational costs" to continue with the investigation between April and September this year.
