Cymdeithas yr Iaith has warned that there will be no radical action to solve the housing crisis in Wales and protect Welsh communities unless people come in large numbers to the Nid yw Cymru ar Werth (Wales is Not For Sale) rally in Blaenau Ffestiniog on May 4 to show the strength of feeling. There are concerns among language campaigners that the Government does not understand the extent of the crisis facing Welsh communities, and that progressive policies to get to the root of the problem will not be adopted.
