The London to South Wales motorway, otherwise known as the M4, runs from Chiswick in the west of London to Pont Abraham Services near Pontarddulais in Sir Gaerfyrddin (that’s Carmarthenshire for monoglots. Ed.). It passes through or close to the major towns and cities of Slough, Reading, Swindon, Bristol, Casnewydd (Newport), Caerdydd (Cardiff) Pen-y-bont ar Ogwr (Bridgend), Port Talbot and Abertawe (Swansea).
Or rather it did: until a traffic report on Sunday in Bristol Live which saw road repairs move it several tens of kilometres south from South Gloucestershire, the unitary authority in which Tormarton is situated to Somerset.
Fact checking is important when reporting the news, except it seems when one works as a Reach plc ‘journalist‘: or the newsroom atlas has inexplicably gone missing; or is non-existent.
