Listen back to some of the highlights of The Last Word from this week, including:

• Independent TD Noel Grealish and Fianna Fáil Senator Lorraine Clifford-Lee were both criticised this week for making comments that were deemed inappropriate. In light of both incidents, we were joined by Lise Hand, Larissa Nolan and Gerard Howlin to discuss what is appropriate for a politician to say.
• Samantha Power, former US Ambassador to the United Nations, discusses her autobiography The Education of an Idealist, her career and her thoughts on Donald Trump's presidency.
• Former Wales and Ireland rugby coach Warren Gatland talks about his history with Ireland, this year's World Cup and the 2021 Lions tour.
