The annual Frontline Emergency and Security Services Parade in Dublin today will honour Caitríona Lucas – the coastguard who lost her life on Monday.

All parties will wear black armbands as they make their way from Parnell Square to Trinity College – with the Coast Guard flag bearing black ribbons.

A book of condolences – manned by Coastguard personnel – will be open to the public in Trinity from 11am until 4pm.
