Michael Portillo resumes his railway exploration of north Wales on the Isle of Anglesey, where the briny waters of the Menai Strait are being used to create a Welsh gastronomic delight.
The island's only railway line delivers Michael to Bodorgan, from which he heads for Oriel Môn at Llangefni, where striking works by the Anglesey-born artist Kyffin Williams are displayed. From Bodorgan, Michael tracks the western coast of the island directly alongside RAF Valley, where RAF and Royal Navy pilots do their fast jet training.
At Wylfa, Michael visits the giant but now defunct nuclear power station to hear how the plant is being decommissioned and the surrounding landscape restored.
