LOUISE Aitken-Walker returned to her Berwickshire home last night

after surviving a horrifying Portuguese Rally accident in which her car

plunged down a ravine into a lake. Both Louise and Swedish co-driver,

Christina Thorner, fought their way out of the sunken car and swam to

safety.

The Scots woman's husband Graham said he was ''absolutely delighted''

that the Vauxhall Astra GTE crew had emerged safe although bruised and

shaken. Graham, a former top rally mechanic added: ''It was a very scary

accident, but Louise was not driving flat out at the time.''

Britain's, and arguably the top international woman rally driver, spun

off a mountain stage on Wednesday in soaking conditions during the

second leg of the world series rally where she was defending her women's

cup world championship lead.

The car rolled down the ravine and plunged into the lake, coming to

rest 30 feet below the surface. Louise, a strong swimmer, said: ''The

car was full of water before it reached the bottom. We got out through a

broken window and started to swim. It seemed an eternity before we got

to the surface.''

Both women clung to a rock until spectators climbed down to rescue

them. A doctor was on the scene within minutes and organised a

helicopter to lift the Vauxhall crew to hospital for a check-up. Early

reports that Louise had broken her jaw proved unfounded but she suffered

shoulder bruising when the rally harness absorbed the impact.

Because Louise was the only woman driver to score points in the Monte

Carlo Rally, her Italian rival, Paulo De Martini, can only draw level if

she finishes in the first 20. The Scottish driver's next event is the

Corsican Rally on May 4.
