First Minister Rhun ap Iorwerth has said that tackling congestion on the M4 motorway requires a "roads-based solution," describing the Brynglas Tunnels in Newport as an "economic problem for Wales."
In an interview with BBC Walescast, the Plaid Cymru leader stopped short of committing to a specific scheme, but stressed the need to address the notorious bottleneck. The previous Labour Welsh government scrapped a controversial plan for an M4 relief road—known as the "black route"—in 2019, citing environmental concerns and costs.
Ap Iorwerth reiterated his party's long-standing opposition to the black route, which would have carved a new motorway across the Gwent levels. However, he said a road-based solution is still needed, potentially alongside new railway stations between Cardiff and the Severn Tunnel. He mentioned the "blue route," which would upgrade an existing dual carriageway south of Newport, as one option.
Critics were quick to respond. Welsh Labour accused the first minister of making an "unfunded transport promise." Conservative MS Natasha Asghar demanded a firm commitment to a relief road, while Reform UK said the road is "desperately needed" and would hold Plaid to account. Wales Green Party leader Anthony Slaughter expressed disappointment, urging investment in sustainable transport instead.
Ap Iorwerth also didn't rule out a third crossing over the Menai Strait, after the Menai Suspension Bridge closed three times in two days due to overweight vehicles. He suggested either a new structure next to the Britannia Bridge or a three-lane model to improve resilience.
In the same interview, the first minister reaffirmed his pledge to end two-year NHS waits within a year, despite his health minister suggesting it could take up to four years. Ap Iorwerth said he remains committed to the original target and will be "honest" about obstacles.
On welfare, ap Iorwerth said the system should not be stigmatized, emphasizing the need to support those who rely on the safety net while helping others regain independence.
