“Having posed as the defenders of the Welsh language for decades, if Plaid fail to give the Welsh language official status, it would be a betrayal of historic proportions.
“The Labour-Plaid government must now sit up and take notice and, even at this late stage, give the Welsh language the status in law that so many have campaigned for decades.
