Sinn Fein should back new police service - Bush envoy

US President George W Bush’s special envoy to Northern Ireland has urged Sinn Fein to give its backing to the North’s new police service.

Ambassador Richard Haas, who is also director of foreign policy planning at the US State Department, said it was time for Sinn Fein to demonstrate their wholehearted support for the peace process by becoming a ‘‘full participant’’ in the Good Friday Agreement.
