How will the impact of Brexit continue to shape the future of the UK and its relationship with the EU? On GZERO World, President and CEO of the International Rescue Committee David Miliband expresses his views on Brexit and the Northern Ireland deal agreed upon by UK Prime Minister Rishi Sunak and European Commission President Ursula von der Leyen. Miliband, who served as the UK's Foreign Secretary from 2007 to 2010, supports the new deal and views it as “more honest than previous ones,” but notes that Brexit is "a journey, not a destination. And it’s forever in its impact.”
