A police review of the Madeleine McCann case is expected to cost nearly £2 million in its first year.

Detectives from the Metropolitan Police's Homicide and Serious Crime Command are carrying out a re-examination of the original investigation into the girl's disappearance in Portugal in May 2007.

Since beginning work last May, the British officers have travelled to Spain and Portugal to pursue lines of inquiry into the disappearance of the youngster from Rothley.

Scotland Yard said it expected to recover £1.9 million from the Home Office for the cost of the Madeleine case review up to the end of March this year, of which it has already claimed for £800,000.

Madeleine was three when she went missing from her family's holiday flat in the resort of Praia da Luz on May 3 2007 as her parents Kate and Gerry dined with friends nearby.

Portuguese detectives, helped by officers from Leicestershire Police, carried out a massive investigation into her disappearance.

But the official inquiry was formally shelved in July 2008 and no police force has been actively looking for her.
