I thank the First Minister for his response. Last week, I chaired a Wales policy forum in Newport on building a western powerhouse, and I was surprised to listen to quite a lot of negative commentary from particularly the Plaid Cymru benches about this. And, yesterday, I think, a Plaid economist said it was 'an attack on the integrity of Wales'. Will the First Minister for the Welsh Government confirm that he supports our working more closely with the west of England, and in particular with Marvin Rees and with Tim Bowles, the two directly-elected mayors we have there, and will he ensure that the Welsh Government, to the extent it has powers, as well as the Cardiff city region, will work with those directly-elected mayors and with the UK Government to do everything possible to ensure we get the best benefit we can from the abolition of the tolls and the strength of the economy over the Severn to link in with us here in south Wales?
