These Regulations make amendments which are consequential on section 54 of the Local Government and Elections (Wales) Act 2021 (“the 2021 Act”). Section 54 requires principal councils (county councils and county borough councils) to appoint a chief executive. This requirement replaces the requirement on principal councils to designate one of their officers as head of their paid service under section 4 of the Local Government and Housing Act 1989 (“the 1989 Act”).
