A MAJOR joint UK-Irish ceremony has begun in Belgium to mark the centenary of a First World War battle where unionist and nationalist soldiers from Ireland fought side by side in the trenches.
The Duke of Cambridge and Irish premier Enda Kenny are at the Island of Ireland Peace Park in Messines in Flanders, to commemorate the first day of the week-long battle.
William and Mr Kenny have been joined by Princess Astrid of Belgium and Lord Dunlop, Parliamentary Under-Secretary of State at the Northern Ireland Office, to honour the soldiers who fought in the battle.
They laid wreaths at the foot of the Round Tower memorial, before meeting invited guests including descendants of those who fought at the Battle.
