He was suspended from the Welsh Labour group in the Senedd on 19 January 2021 after allegedly drinking alcohol on Senedd premises while a ban on alcohol sales was in force throughout Wales. The incident happened on 8 December 2020 when Alun Davies met with conservative members Paul Davies, Darren Millar and Nick Ramsay over alcohol in a Tŷ Hywel tearoom to seek their support on his Bill, Welsh Hearts Bill. The Senedd Commssion said it was investigating the incident which "may have been contrary to public health regulations". Welsh Government brought in COVID-19 regulations on 4 December 2020, banning the sale of alcohol in licensed premises. At the time of the suspension Alun Davies said he was sorry that the incident gave the impression that he was not upholding the regulations, adding that "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."
