The Welsh Assembly's bid for a super-fast broadband pilot to be based in the principality lacked sufficient effort and quality, a leaked report has indicated.
Last month, Chancellor George Osborne announced that trial schemes will go ahead in the Highlands and Islands, North Yorkshire, Cumbria and Herefordshire, with Wales among the regions to miss out.
And according to a Department for Culture, Media and Sport document received by the Western Mail, "it was evident from the proposal that we received from the Welsh Assembly Government that they had not put much effort into applying for a pilot".
"There was more text in one answer box in the Herefordshire proposal than in the entire Welsh proposal," the government feedback said.
The document stated that the potential lack of competitive tension, the difficulty of applying lessons learned elsewhere and the lack of diversity of lessons learned in Wales meant that the other proposals were "more attractive as pilots".
However, the Welsh Assembly has reacted angrily to the comments, saying the criticism was "wholly unjustified", the Western Mail reported.
