A new electric fence has been installed at Buckingham Palace. The unprecedented move - the first time such drastic security measures have been taken - comes in the wake of the "Batman on the balcony" fiasco.
Electric fences may also be erected around the perimeters of other royal residences like Windsor Castle.
The new fence at Buckingham Palace blocks off the parapet and roof at the side where Fathers 4 Justice protester Jason Hatch, dressed as Batman, clambered on to a ledge last month.
Engineers spent five hours welding the new fence in place before the current was switched on. A senior police source said: "This is a visible part of a radical change in royal security. There also needs to be a radical change in the way the royal family think about security."
