Sunday Supplement

With Andy Burnham and Wes Streeting gunning for Sir Keir Starmer's job, Labour's Lord Peter Hain explains how his party got into such a bind. Plaid Cymru's first ever Welsh government has been formed. New culture and sport minister Heledd Fychan joins us in the studio. Reform gained 34 Senedd members in last week's election. Their leader Dan Thomas tells us his plans for the seventh Senedd. Where Reform succeeded, the Conservatives failed. Why? Former Conservative secretary of state for Wales Robert Buckland has ideas what went wrong, and how to put it right. And 100 years after the 1926 general strike came to an end, reader Stephanie Ward of Cardiff University reminds us how it all unfolded, and its significance.
Two new Senedd members join us to tell us all about themselves: married couple Gwyn Williams and Safa Elhassan, two of Plaid Cymru's three members for Gwyr Abertawe.

Plaid Cymru leader and prospective new First Minister Rhun ap Iorwerth, Welsh Labour's new acting leader, Ken Skates, academics Richard Wyn Jones and Deian Hopkin, former SNP Westminster leader Ian Blackford and two Senedd newbies, Reform's Joe Martin and Plaid Cymru's Kiera Marshall join us to discuss last Thursday's election result.

It's a special election programme this week, with Professors Richard Wyn Jones and Ailsa Henderson and the BBC's Alex Forsyth dissecting the polls and ups and downs of the parties ahead of the Senedd, Holyrood and English local government elections. We'll have watchers of all colours telling us how the campaign has gone for them on the ground: Leanne Wood, Mark Williams, Sean Morgan, Wayne David, Gawain Towler and Lauren McEvatt.

After another difficult week for the Prime Minister, the Times' Patrick Maguire discusses his position. The ceasefires continue but what is happening with talks to end the hostilities in the Middle East? We have international peace negotiator Nomi Bar Yaakov on the programme. Education is fully devolved yet little has been said about it during the Senedd campaign. Lucy Crehan from the Centre for Education Systems and the general secretary of the teaching union UCAC talk about the new curriculum for Wales. Most parties claim to have fully costed manifestos, but are their financial plans workable? Guto Ifan from the Wales Governance Centres takes us through the figures. Des Clifford is a former civil servant and has published a booklet called Slouching Toward Cardiff Bay. He's with us to discuss the past 27 years of devolution and the challenges ahead for the next Senedd.
And in the last in our series of leader interviews, Labour's Eluned Morgan joins us.

With the latest revelations on vetting Mandelson and what the Prime Minister did and didn't know, the FT's political editor George Parker updates us. Israel have agreed a 10 day ceasefire with Lebanon. What does this mean for the fragile ceasefire in Iran? Former foreign office minister Kim Howells discusses. How should the next Welsh government deal with the health service? The Royal College of Surgeons' Jon Barry and Dr Helen Howson from the Bevan Commission have some ideas. The Senedd manifestos are all in, and every party has made their offer on improving housing stock in Wales. The Bevan Foundation's head of policy Mabli Jones is with us to tell us what the issues are. And what's happened to the 6,500 non-conformist chapels that were all over Wales at one point? The Royal Commission on the Ancient and Historical Monuments of Wales believe only around 1,500 are still in use as places of worship. Susan Fielding talks about the plan to hold a census of church buildings to see what's happened to them all.
And in our penultimate leader interview, it's Plaid Cymru Rhun ap Iorwerth's turn.
