Spokesman Clarence Mitchell on Madeleine McCann search
The Metropolitan Police are to "bring their expertise" to the search for Madeleine McCann, the Home Office says.
Madeleine went missing aged three on holiday in Portugal in May 2007. Downing Street said David Cameron had written to Kate and Gerry McCann to tell them that Scotland Yard had been asked to "cast a fresh eye" over evidence.
The family's spokesman, Clarence Mitchell, told the BBC News Channel they welcomed the Met Police commitment.
