Career
Elected from the North Wales Regional list, he was Shadow Minister for Rural Affairs from 2007 to 2011. Williams, who was a farmer from North Wales, was a colourful political figure who was respected for his straight talking and campaigning on rural issues. Although privately he admitted he never saw himself as a politician.
Williams rise to prominence began in 1997-1998 when he joined protesters blockading the Portuguese of Holyhead on Anglesey over the importation of Irish beef.
He later became a leader in the United Kingdom fuel protests in 2000. Williams was first elected to the Welsh Assembly on 1 May 2003 and was re-elected in 2007.
Serving until his death in 2011. He was Shadow Minister for Rural Affairs from 14 July 2007 and sat on the Sustainability, Rural Development, and Standards committees.
Williams had also been the Conservative spokesman for Environment, Planning and Countryside and Local Government in the Second Assembly (2003-2007), during which time he was Chair of the North Wales Regional Committee.
Following the news of his death, First Minister and Welsh Labour leader, Carwyn Jones described Williams as a "colourful" but "tough battler". Williams was diagnosed with colon cancer in the summer of 2010. He died in April 2011 after an eight-month battle with the disease.
In May 2012, an inquest into Williams" death heard that misdiagnosis of the cancer resulted in a five-month delay in its treatment.
Williams was initially told by the Betsi Cadwaladr University Health Board that he had an ulcerative colitis in April 2010, five months before the colon cancer was correctly identified. The coroner concluded that the delay may have allowed him to "live longer but not necessarily have been cured".
The case is now subject to a legal action by the Williams family. Since 2011 the Brynle Williams Memorial Award has been presented at the Royal Welsh Show by the Welsh Government"s Department for Agriculture.
The award was established in honour of Williams" contribution to Welsh agriculture as both an Department of Administration and Management and an active farmer.
