The family of a woman killed when a rally car ploughed into a group of spectators have said she will be "missed immensely".

Elizabeth Allan, 63, known as Betty Allan, was one of three people killed after the car came off the road at the Jim Clark Rally in the Scottish Borders on Saturday afternoon.

She had travelled to the event from Barrhead in East Renfrewshire with her partner, Iain Provan, 64, who founded the Motorsport Scotland website.

In a statement released through Police Scotland, her family said: "Betty was a caring and loving daughter, sister, aunty and great-aunt, and will be missed immensely."

The other man who died was Len Stern, 71, from Bearsden in East Dunbartonshire. His family said "he died watching the sport he loved".

About 250 competitors had been taking part in the rally, one of the largest in the UK.

An investigation into the circumstances of the crash is continuing.

The rally is named after Scottish Formula One driver Jim Clark, who grew up in the area and was killed in an accident in Hockenheim, Germany, in 1968.

Police have appealed for witnesses to the fatal crash, and an earlier one near Eccles, to contact them.

Detective Superintendent Kenneth Graham said: "We would ask that anyone who has any video footage or photographs, or has any other information that may help with our investigation, to contact police immediately on 101."

Police will carry out a review of safety at public events in Scotland following the deaths, Justice Secretary Kenny MacAskill announced yesterday.

The Scottish Government will also commission a review of motorsport event safety in the country in light of the tragedy.
