Portsmouth parking wardens in workload and pay dispute

More than half of Portsmouth's parking wardens did not work on Monday, due to a day of industrial action.
During peak times the city should have been patrolled by 18 officers - instead there were just eight.
Staff are concerned about changes to their workload. Portsmouth City Council said parking regulations would continue to be enforced across the city.
