Send articleLondon 2012: "100 days of peace" campaign is launched
The Olympics must be remembered "for peace as well as sport", the brother of a teenager killed in London has said. George Mizen, 12, is joining thousands of British children from nearly 500 Catholic schools in London, Essex, Kent and Hertfordshire to call for "100 days of peace" around next year's Games.
The schoolboy lost his brother Jimmy, 16, when he was stabbed at a bakery in Lee, south-east London, in May 2008. A mass will be held at Westminster Cathedral later to launch the campaign.
