A peace walk took place from Belfast to Dublin earlier this week and arrived in the capital today. One of the participants was Conservative peer Lord Michael Bates who revealed last night that "aggressiveness, intolerance and incivility" over Brexit led him to quit as a Government Minister.  Well, Lord Michael Bates joined Ivan in studio to discuss his reasons behind his resignation and Brexit, the horrendous murder of journalist Lyra McKee and the challenges to peace in Northern Ireland.
