Standing ovation at #LyraMcKee's funeral as priest issues challenge to political leaders. Will it make a difference?

We've had countless big funerals for victims of terrorism. We've had thousands of powerful sermons from the pulpit. But few have been as remarkable as the effect of yesterday's homily by Father Martin Magill at the funeral of murdered journalist Lyra McKee. With the Prime Minister and Taoiseach looking on, he issued a direct challenge to the Northern Ireland party leaders sitting in the front row at St Anne's cathedral. What impact will those words - and the standing ovation that followed - have on the politicians? Stephen spoke to Reverend Harold Good, the former Moderator of the Methodist Church who's been a key figure in peacemaking, the Newsletter's political editor Sam McBride and the Irish News security correspondent Allison Morris.
