Grace Campbell won a landmark case to stop corporal punishment in Scottish schools in 1983.

Most Scots at the time still supported 'the belt', making it a controversial decision from the European Court of Human Rights.

Witness speaks to her son, Andrew Campbell, who remembers fearing the belt, and how his mother went about changing the law.

Witness: The stories of our times told by the people who were there.
