Adam Boulton and guests reflect on sobering week in Northern Ireland following the murder of the journalist Lyra McKee. Remarks at her funeral have reignited the debate over the future of a power sharing government and an end to violence on the streets. Also this week, as the the Extinction Rebellion protests reach their conclusion, have their efforts helped or hindered the climate change cause? And with the European Parliament elections (potentially) on the horizon, the panel assess the prospects of Change UK following its campaign launch this week. Joining Adam are Sky's senior Ireland correspondent David Blevins, talkRADIO presenter Julia Hartley-Brewer, author of The Climate Majority Leo Barasi, Sky's political reporter Rob Powell and the head of Sky Data Harry Carr.
