on the value of the homes of local people". In contrast, by fall 2001 the Exmoor National Park authority in England began limiting home ownership there which was also driving up local housing prices by as much as 31%. Elfyn Llwyd, Plaid Cymru's parliamentary group leader, said that the issues in Exmoor National Park were the same as in Wales, however in Wales there is the added dimension of language and culture. Reflecting on the controversy Glyn's comments caused earlier in the year, Llwyd observed "What is interesting is of course it is fine for Exmoor to defend their community but in Wales when you try to say these things it is called racist..." Llwyd called on other parties to join in a debate to bring the Exmoor experience to Wales when he said "... I really do ask them and I plead with them to come around the table and talk about the Exmoor suggestion and see if we can now bring it into Wales".

According to planners in Snowdonia and Pembroke applicants for new homes must demonstrate a proven local need or the applicant had strong links with the area. In the 2001 General Election, Plaid Cymru lost Jones' old seat of Ynys Môn to Labour's Albert Owen. An internal report commissioned by Plaid Cymru following the 2001 General Election attributed the loss of significant votes directly to Glyn's controversial comments. Despite this, Plaid Cymru recorded their highest ever vote share in a General Election of 14.3%, gaining Carmarthen East and Dinefwr and electing Adam Price. 2001 Census and tickbox controversy see also Demography of Wales, Welsh people According to the 2001 census the number of Welsh speakers in Wales increased for the first time in 100 years, with 20.5% in a population of over 2.9 million claiming fluency in Welsh, or one in five. Additionally, 28% of the population of Wales claimed to understand Welsh. The census revealed that the increase was most significant in urban areas; such as Cardiff (Caerdydd) with an increase from 6.6% in 1991 to 10.9% in 2001, and Rhondda Cynon Taff with an increase from 9% in 1991 to 12.3% in 2001. However, the percentage
