EVERY WEEKDAY evening, TheJournal.ie brings you the five things you need to know by 5pm.

1. #REFERENDUM: Fine Gael town councillor and Mayor of Longford Jim Keogh is going against his party and calling for a ‘no’ vote in the Fiscal Compact referendum. Keogh told TheJournal.ie today that one of his main reasons for voting against the treaty is because he hasn’t seen the government make an effort to writedown Ireland’s bank debt.

2. #GREEN LIGHT: TheJournal.ie has learned that a small green light being fitted to a number of taxis in Dublin may be intended to signal to potential customers and other drivers that they are being driven by an Irish person.

3. #LEGAL ACTION: A Panamanian fisherman is suing a cruise ship which sailed past him and his two friends as they drifted in the Pacific Ocean. Passengers on board say they alerted staff members to the stranded fishermen. Adrian Vasquez, 18, watched both of his friends die after the ship had passed.
