Diana, Princess of Wales
As well as working on charities such as AIDS she lent her name to the campaign to ban landmines. Her personal support is said to have been a significant factor in encouraging Britain and then other countries to support the Ottawa Treaty which sought to introduce a ban on the use of anti-personnel landmines. When Robin Cook brought the second reading of the landmines bill to the house in 1998 he made a point of paying tribute to the contribution of Princess Diana.
