The mother of an 18-year-old girl who died in a road accident in Argyll and Bute has paid tribute to her "perfect daughter".

Amy Simpson from Cowdenbeath was driving near the village of Dalavich at around 6.40pm on Tuesday when her car came off the road.

The vehicle plunged into the River Avich, killing Ms Simpson. Four female passengers, aged between 17 and 19, managed to get to safety without serious injury.

The teenager's mother, Angela Simpson, said on Thursday: "My gorgeous girl Amy wasn't just the perfect daughter, she was my best friend, my soulmate and my rock and she made me so proud.

"One day I will make her as proud of me as I was of her. I am absolutely heartbroken and it's hard to find the words at this distressing time to express just how much I will miss her."

Inquiries are continuing into the circumstances of the crash.
