The Welsh Parliament has launched a probe into whether four politicians' late-night drinks broke Covid rules.

Three Conservatives and one Labour Assembly Member have apologised after the gathering last month at the Senedd in Cardiff.

The politicians were meeting to discuss Labour member Alun Davies' plan for a Welsh Hearts Bill to boost defibrillators in rural areas.

ITV News reported the gathering took place on December 8 - four days after Wales’ government banned pubs and restaurants from serving alcohol after 6pm.

A source told the Mirror alcohol was consumed at the meeting in the Tŷ Hywel building, attached to the Senedd complex, and it went on until around midnight.

Yet those present insist they didn't break the rules, which banned hospitality venues from serving alcohol but not people from drinking it. The Senedd Commission is now investigating whether the gathering broke any rules.

The three Tory members - Welsh Conservatives leader Paul Davies, Chief Whip Darren Millar and Nick Ramsay - tonight apologised and admitted they did not follow the "spirit" of the rules.

.They said in a statement: "We are profoundly sorry for our actions.

"While we did not break the rules, we recognise that what was part of a day’s work would not be seen to be following the spirit of them, especially given the tough time the country has been going through."

Labour Assembly Member Alun Davies was tonight suspended from the party whip and apologised for the “impression” he gave voters by attending.

But he also defended his actions, saying the Commission had already told him he did not breach the regulations on food or drink.

The three Conservatives have not been suspended from the whip.

If the Senedd Commission deems the members’ code of conduct was breached, it can refer the matter to the independent standards commissioner for Wales.

A spokesman for the Senedd Commission said: “We are aware of an incident on the Senedd estate last month which may have been contrary to public health regulations in force at the time.

“The Senedd Commission takes the public health regulations in Wales very seriously and is currently investigating the matter in order to establish an accurate account of what took place and to determine whether action may be required.”

A spokesperson for the Senedd Labour Group said: “A member has been suspended from the privileges of Senedd Labour Group membership while an investigation takes place into this alleged incident.”

Mr Davies said: “I am very sorry if my actions have given the impression that I am in any way not committed to upholding the regulations which I have consistently supported throughout the last year.

“For context, the purpose of this meeting from my perspective was to seek to persuade the Welsh Conservatives to support my proposal for a “Welsh Hearts Bill” which the Senedd endorsed on 21 October and to make a commitment to enact this life-saving legislation in their manifesto for May’s election. This is part of my work across political parties on this issue.

“The Senedd Commission has already confirmed to me that I did not breach the Coronavirus regulations on the consumption of either food or alcohol that were in force at that time.

“I have also confirmed to the Commission that the regulations on the number of people present and on social distancing were not breached either. I look forward to the Commission’s final conclusions on this matter.”
