I'm surprised to hear the Cabinet Secretary criticise the UK Government for lack of openness and transparency in this respect, because researchers from my office on 13 October made a similar request to the Welsh Government—to the First Minister—to publish documents relating to the Welsh Government's understanding of the impact of Brexit upon Wales, and the response that we got was this:

'The negotiations on the UK's withdrawal from the EU are ongoing with no clear indication of what the resulting situation will be. The Welsh Government is exploring a range of potential outcomes and implications for Wales and the work is in constant development as negotiations progress and is therefore incomplete. I do not believe that releasing information at this stage would be in the wider public interest.' 

So, isn't the Cabinet Secretary's response to the leader of Plaid Cymru hypocrisy of a high order?
