A NATIONAL assembly with powers broadly equivalent to those of the Scottish Parliament would give the people of Cornwall the government they "need and deserve", says Mebyon Kernow.
The party launched its White Paper on St Piran's Day and the deputy leader and Cornwall councillor for Callington Andrew Long said: "The time has come for us to press again to allow the people of Cornwall to decide their future."
Speaking at a reception at The County Arms in Truro, Mr Long, unveiled the party's 28-page consultation document, Towards A National Assembly Of Cornwall.
Under MK's plans, the assembly would control the majority of the public sector in Cornwall, including the NHS, education, a wide range of public bodies and local government.
The launch, compèred by Cornwall councillor Loveday Jenkin, was addressed by three of the party's prospective parliamentary candidates.
Rob Simmons, a member of Penzance Town Council, set out the background to Cornwall's claim for devolution, recalling 2000's 50,000-name petition for a Cornish assembly.
However, describing "talk of Celtic kingdoms, Dumnonia and the setting of the Tamar border in the 10th century" as "matters for historians", Mr Simmons said today's task was to focus on the "modern fight for self- determination".
Stephen Richardson, who sits on Illogan Parish Council, appealed to people to get involved in the consultation process.
He said: "We want to hear from anyone who believes, like us, that Cornwall should have enhanced powers to take democratic decisions on the matters that affect us all.
"We recognise there are groups and individuals that may believe in Cornish self-government, but who think differently to us about exactly what we should be aiming for and how we should achieve it. So let's talk about our ideas and yours. Let's see where there is a consensus and where we can work towards achieving one."
Under MK's proposals, the unitary Cornwall Council would be replaced by an assembly of 40 members elected by proportional representation. In addition, it would create four unitary "district" bodies.
Towards A National Assembly Of Cornwall sets out 72 ideas, facts and principles, ranging from tackling Cornwall's "democratic deficit" and the benefits of devolution to the financial implications and relationships with public bodies.
