Bonfires will be lit in loyalist areas across Northern Ireland later to usher in the main date in the Protestant loyal order parading season.

Some of the pyres, mainly constructed by stacking wooden pallets, have already been torched in recent nights – but the vast majority will be ignited late on Tuesday night.
