Peace activists have set out on a three-week “Long March on Newport” to protest against September’s NATO Summit. Police say they have drafted in 9,000 officers to face the protesters in one of the UK’s biggest ever police operations.

More than 20,000 activists from around the world are expected to take part in demonstrations during the summit, where a week-long peace camp and a counter summit are among some of the events planned in what has been billed as Wales’ largest protest in a generation.
