The Union flag is flying over Belfast's city hall to mark a royal birthday.\n\nLoyalists are expected to demonstrate at the landmark as the flag is raised for the second time since city councillors voted to restrict the number of days it can fly to 18.\n\nThe flag was hoisted at dawn to mark the 48th birthday of the Earl of Wessex's wife Sophie.\n\nMeanwhile police said two men arrested on Saturday during protests in east Belfast over the flag controversy will be brought before magistrates on Monday.\n\nAn 18-year-old was charged with disorderly behaviour and a 20-year-old with disorderly behaviour and provocative conduct. A teenage boy who was detained was released unconditionally.\n\nEarlier
