The People Power rally in Trafalgar Square followed the demonstration by 250,000 people in Brussels last weekend demanding more action to protect children in Belgium.
The organisers of yesterday's event included Beverley Palmer, whose daughter Rosie, three, was murdered in Hartlepool, Cleveland, after going a few yards from her house to buy an ice cream. Ms Palmer said: "I want official recognition to be reintroduced for the term psychopath. It is not enough for courts to be told men have personality disorders, a term not recognised in medicine."Reuse content
