Caerphilly Senedd Member Hefin David died as a result of suicide, an inquest has concluded.

Dr David’s body was found at his home in Nelson, on Tuesday August 12, last year – the day before what would have been his 48th birthday.

The inquest was concluded in writing by Gwent Senior Coroner Caroline Saunders under a relatively new procedure to hold inquests without a public hearing.

In a statement of fact, which accompanied the Record of Inquest, Ms Saunders said Dr David had been prescribed antidepressant medication in October 2021, but had stopped taking it at the end of May 2025.

Ms Farmer wrote this resulted in a downturn in his mental health and added there was no third-party involvement and neither drugs nor alcohol had influenced his decision to take his own life.

She wrote: “Hefin did not disclose the depth of his depression. To family and work colleagues he continued to be working hard and making plans for the future. He did not disclose any thoughts to end his life.”

“A devoted father”

In a statement released through Welsh Labour after the inquest was opened and adjourned last year, Dr David’s family described him as a “devoted father”.

“It is clear from the very many messages we have received that Hefin was widely respected and held in genuine affection by the community he represented, and by those he worked with during his many years of public service.

“But more than this, Hefin was a devoted father who was adored by his daughters Caitlin and Holly, a much loved son to Wynne and Christine, a beloved brother to Siân, a brilliant uncle to Osian and Catrin, and a soulmate to his cherished partner Vikki.

“We are very grateful to all those who have reached out to us since Hefin’s passing, and ask now for privacy to grieve.”

A life serving his community

Having served Caerphilly in the Senedd over the last nine years, Hefin’s role saw him touch the lives of countless people, organisations, and businesses across the area he so proudly represented.

Born in Caerphilly Miners’ Hospital, Hefin David grew up in Penpedairheol and attended Heolddu Comprehensive School in Bargoed.

Growing up during the miners’ strike, Hefin had a regular upbringing flavoured with politics. Aged only five or six, he would deliver leaflets out campaigning with his father, Wynne David, a Labour councillor and headteacher of his primary school.

He studied at Cardiff University, where he earned degrees in economics and politics, and European policy. He also studied at the University of Wales in Newport, and the University of Gloucestershire, where he gained teaching qualifications.

He later worked as a senior lecturer at Cardiff Metropolitan University, where he taught human resource management and professional practice. He also taught abroad in Germany, Greece, India, and China.

Hefin’s political career began in March 2007, when he won a by-election to represent the St Cattwg ward – a ward also represented by his father.

After a decade on the council, Hefin was elected to the then-National Assembly for Wales to represent the Caerphilly constituency in 2016 – succeeding Jeff Cuthbert, who stepped down at that election.

He was re-elected to the Senedd with an increased vote share in 2021.

In the Senedd, Hefin campaigned on many issues. He sided with leaseholders against ‘fleecehold’ estate management charges, particularly on the Cwm Calon estate near Ystrad Mynach.

He also championed rail transport improvements, support for people with Long Covid, and justice for the victims of the infected blood scandal.

Other areas he focused on during his time in the Welsh Parliament were employment and education. In 2023, he wrote a report for the Welsh Government looking into the relationships between education providers, industries, and employers, and ways to improve the transition between education and employment.

But most notably, he was a passionate advocate for people with autism and additional learning needs (ALN).

He had strong relationships with ALN community groups like Sparrows and Valley Daffodils, and had also been a governor at Trinity Fields School in Ystrad Mynach.

As the doting father of two girls – one of whom has autism – it meant this was a cause very close to his heart – and he worked tirelessly to make Wales a better place for people with autism and ALN, and their families.

More recently, he has worked as a Senedd commissioner with responsibility for finance. As part of that role, he pushed through the Senedd Commission’s £84m budget for 2025/26, which laid the groundwork for the Welsh Parliament’s expansion to 96 members next May.

It was a role Hefin took on with “diligence and skill”, according to the Senedd’s speaker or Llywydd, Elin Jones  – who paid tribute to him and said: “Hefin was particularly well-liked across the Senedd.”

He served in the Senedd alongside his partner Vikki Howells, who is the Labour MS for Cynon Valley.

He was also a friend to many within the Senedd, regardless of political beliefs, and considered himself a “critical friend” to the Welsh Government – unafraid to speak out against the party line where he felt it was needed.

While being a proud member of Welsh Labour, Hefin could form friendships across the political divide, and enjoyed friendly political duels with political rivals.

Away from politics, Hefin was a much loved and respected member of his community, and was a supporter of a variety of groups, organisations, and businesses up and down the constituency.

Some of these include Ysbyty Ystrad Fawr FM (YYFM), where he had his own podcast series – Caerffili’s Heroes – shining a light on various individuals and groups making a difference in the community.
