Radio failure claims rejected in royal attack

Police have rejected suggestions that a communication breakdown led to the Prince of Wales and Duchess of Cornwall being caught up in student protests.
It has been reported that police guarding the couple were using a different radio frequency to those policing the London demonstrations.
Scotland Yard insisted the two teams were in contact and may have used mobile phones or e-mail.
A major inquiry into the student disorder of recent weeks has begun.
'Intent on violence'
The prince's and the Duchess of Cornwall's car was daubed with paint and had a window smashed during tuition fee protests on Thursday.
The royal couple were being escorted by outriders and Royalty Protection Officers to a theatre in central London when their car was attacked.
A police spokesman said the route along Regent Street had been checked minutes before the incident and was deemed to be safe.
