Welsh First Minister Mark Drakeford has said he would dispute the use of the internal markets act to stop the Scottish Government including glass in its deposit return scheme.
Speaking to the BBC , Drakeford said if the UK-wide legislation is invoked in this way it would be “very serious questions”.
Wales, who had intended to go ahead with their deposit return scheme which includes glass, may no longer be able to do this after the UK Government stepped in to say the Scottish Government could not have glass in theirs.
