It's discrimination introduced by the WAGs (Welsh Assembly Government) to keep us borders out of "their" jobs.
Personally I think we have grounds of complaint on discrimination grounds as we are not Welsh enough and neither are we English enough to be counted as English. I say blow you all we're going UDI. We will then set up roadblocks on the M4 and charge both the Welsh and the English to cross our ground or force them to build an M4 bypass around us to avoid paying.
P.S. My wife's first language is Welsh she only started to learn English when she went to school aged 5 and she doesn't know what level 2 Welsh is either.
