An ambulance campaigner says the Welsh Assembly has failed Monmouth.

Mat Davies is still fighting for the Assembly to hold a scrutiny inquiry 18 months after a coroner found failings in the ambulance service contributed to the death of his mum, Jackie.

"I launched a petition after a public meeting in January 2012," said Mr Davies.

"It called for a scrutiny inquiry which would have been concerned with identifying failures regarding accountability and transparency of data.

"Firstly, my aim was to encourage the health committee to listen to a wide range of voices that could then put pressure on the Health Minister to respond.

"Despite the emotional strain this took given my personal interest in the subject, I remained focused, and with the long game in mind.

"Therefore, I worked out how we could improve ambulatory care in Monmouth. At least I thought I did.

"That petition was signed by 450 people and was later supported by Monmouth, Chepstow and Abergavenny town councils.

"Months soldiered on and response times for Monmouth continued to be missed. Councillors joined me in meeting members of the ambulance service including its chairman.

"However, the health committee was silent. Then, last November the sad case of the death of a baby after a two-hour ambulance wait was brought up in the Senedd.

"The then Health Minister, Lesley Griffiths, immediately launched a review into the trust. That review concluded in April of this year, and identified a 'culture of fear' within the service.

"The review was limited in scope, and therefore I believed that it was necessary to still hold a scrutiny inquiry.

"Two members of the committee considered how they could 'manage public expectations' and discussed setting up a secondary consultation process.

"This saga became Kafkaesque in the extreme, and the real victims are the paramedics, tax payers, and those on the receiving end of service failure.

"My experience of the Welsh Government and Assembly reminds me of being a child and playing musical chairs.

"Accountability, and getting things done, gets lost in the on-going turn-over of roles and responsibilities.

"This experience has confirmed that beyond the smoke screen of green papers, petitions committees and so on, short-term political interests override the capacity to have an honest discussion about the ambulance service.

"Know this; the people of Monmouth have been wronged, and deserve better.

"I will continue to campaign on this issue in the memory of my mother and the people of Monmouth.

"But I am deeply sorry that as a community, we have been let down. The failure of the Assembly is clear.

"For the values we share, and the community we adore, we must never give up. I hope that the autumn session in the Assembly will involve a scrutiny inquiry."
