Plaid Cymru MS Rhys ab Owen has said that the Senedd must be "empowered" so that it is ready to take on the role as the legislature of an independent Welsh state.
Writing in the Sunday Times, The Plaid Cymru Spokesperson on the Constitution, said: "Our Senedd must be empowered to take on the role it will inevitably play in the decades to come as the home of Welsh democracy and the legislature of a future independent Welsh state."
Mr ab Owen also warned that devolution is "under attack from Boris Johnson’s sleaze ridden Tory government", despite the fact that "the home of Welsh democracy has the full mandate of the people of Wales",
He said: "Westminster's reaction to this mandate [Wales voting by a margin of more than 2:1 for parties that stood on a platform of greater powers for the Senedd] so far has been not just to ignore it but to seek to reverse it. They have a plan for Wales; it just doesn't involve us.
"Devolution - that most basic democratic principle that decisions affecting Wales should be made in Wales - is under attack from Boris Johnson’s sleaze ridden Tory government.
Funding - snatched. Devolved powers - grabbed. And the number of Welsh MPs to be cut by a fifth".
Mr ab Owen said that the time has come to send a "clear message to Westminster that the Senedd is here to stay" through strengthening and expanding the Senedd.
"It’s not about more politicians. It’s about super-powering our parliament – making it fit to represent our people. Ensuring that the seat of power over Wales, resides in Wales, and not in another country.
With devolution under threat from this Conservative UK Government, we must send a clear message to Westminster that the Senedd is here to stay and decisions about Wales are made in Wales".
