Cornish devolution

Some level of Cornish independence may have continued into the 10th century, consistent with William of Malmesbury's account of King Æthelstan's expulsion of the Britons from Exeter and establishment of the River Tamar as the boundary between Cornwall and Wessex.

[6] In 1497, Michael Joseph An Gof and Thomas Flamank and a Cornish army marched upon London in protest of raised taxes by Henry VII who aimed to increase funding for a war against the Scots.

Between 5 March 2000 and December 2001, the campaign collected the signatures of 41,650 Cornish residents endorsing the call for a devolved assembly, along with 8,896 signatories from outside Cornwall.

[11] A report by the Institute for Public Policy Research (IPPR), an independent think tank, suggested that Cornwall has "outgrown" the original devolution deal of 2015.

[15] The powers were designed to give the council and Mayor/Meryon "greater control over transport budgets, building, skills delivery, and greater influence with government to tackle challenges of second homes"[16][17][18] The council announced in April 2023, it would be abandoning the proposed devolution deal and the role of a directly elected mayor due to public opposition.

[23] On the 16 October 2024 Ben Maguire called on the government to give Cornwall a devolved Cornish Assembly, Labour MP Perran Moon also made a similar appeal for a deal akin to Wales.
