He is president and chair of a Christian charity, the Evan Roberts Institute, which has attracted controversy in the past for financial links with the church of a pastor called Yang Tuck Yoong, who was reported to police in 2013 for his comments on homosexuality, which he called a “sin” and an “abomination”.
The controversy was raised again in the summer this year, when Millar stood unsuccessfully at the general election for the Clwyd North seat.
Millar said then he does not endorse the pastor’s views and “no one should be discriminated against on the basis of their sexual orientation or religious beliefs”.
The MS suffered a setback in late 2020, when he temporarily quit his front-bench after he and three other Senedd members were seen drinking on Welsh Parliament premises during the pandemic.
The then Conservative group leader Paul Davies also resigned at the time, marking the return of Andrew RT Davies for his second stint as group leader.
Millar returned as chief whip after the May 2021 Senedd election and the four politicians were cleared of any wrongdoing.
