'Effigies' trio held by police
Protesters thought to have been planning to behead effigies at the royal wedding have been arrested, sources said.
Police seized a guillotine as they arrested two men - aged 68 and 45 - and a 68-year-old woman thought to have been plotting disruption on the big day.
It is understood one of the men arrested is Chris Knight, 68, head of the anti-royal anarchist group The Government of the Dead.
The arrests in Brockley, south-east London, come after officers warned there would be a number of pre-emptive arrests on the eve of the big day.
The trio were being held in a south London police station.
Scotland Yard, which has vowed to deal "robustly" with suspected troublemakers, is believed to be concerned about activities by anarchist groups.
