It's been a busy Summer of politics and the pace is not letting up as the Senedd returns from recess. So there's plenty for Felicity Evans to pour over with BBC Wales political editor Gareth Lewis, his Wales Online counterpart Ruth Mosalski, Cardiff University's polls expert Dr Jac Larner and BBC Wales Parliamentary reporter Emilia Belli. Among the topics under discussion are the latest Welsh opinion poll and the up-and-coming Caerphilly Senedd by-election plus the prospects for the Chancellor's budget in November and the Welsh General Election next May.
