Guardian questions Home Office claim that revealing royal security cost is risky

At freedom of information tribunal, Guardian says it has not been publicly explained how such data might be useful to attackers

The news organisation has brought a legal case arguing that disclosure of the figure would enable a more informed public discussion about the costs and benefits of the monarchy.
