24-26 September 2023: I travelled to Boston, USA to participate in a panel debate as part of an event to mark the Good Friday Agreement 25th Anniversary, which was organised by the Edward M. Kennedy Institute for the United States Senate. The cost of return flights (£842.78), two nights’ accommodation (US$853.08) and transfer costs from the hotel to the Institute (US$60) were met by the Edward M. Kennedy Institute.
