British police ready for protests as Bahrain king arrives

Protesters angry about the treatment of anti-regime activists in Bahrain are also expected to be present when he joins the Queen at Sunday's Royal Windsor Horse Show, west of London.
The king will be accompanied by his son, Prince Nasser bin Hamad, who faces a London court bid to overturn his immunity from prosecution over torture allegations.
The case was brought by a Bahraini refuge, who claims the prince tortured anti-regime demonstrators during a crackdown against the uprising in 2011.
The Bahraini embassy in London called the claims "unfounded, false and politically motivated", according to the London Times.
