Former rugby star Roy Laidlaw reveals dementia battle

Roy Laidlaw, the former Scottish and British & Irish Lions rugby player, has revealed he has dementia.

The scrum-half believes the condition is a consequence of being a smaller player who had to do a lot of tackling in his career.

In recent years there has been growing evidence that repeated head injury in contact sports might lead to long-term brain damage.

But despite his challenges Laidlaw said he had "no regrets".
