British police have confirmed former world rally driver Colin McRae and his five-year-old son were among the four people killed in yesterday's helicopter crash in Scotland.

British air investigators have started examining the wreckage.

The helicopter, which belonged to Colin McRae and which it is thought was being piloted by him at the time, crashed yesterday afternoon in a wooded area near the McRae family home in Lanark, south of Glasgow.

There were three other people on board. No-one survived.

Strathclyde police hope to confirm the identities of all four victims later today.

During his distinguished rallying career, Colin McRae won the Circuit of Ireland and was twice British champion before becoming the first Briton to win the world rally championship drivers' title in 1995.

He was married with two young children.

According to friends and neighbours, Mr McRae was a keen experienced helicopter pilot who flew regularly to and from his home and knew the terrain well.
