In a written statement 19 June 2018, I confirmed that the Welsh Ministers (Transfer of Functions) Order 2018 had come into force from 24 May. This was part of the package of reforms to Wales’ constitutional settlement under the Wales Act 2017 and included the transfer of the executive functions under Part 1 of the Civil Contingencies Act 2004.
