The split with Mebyon Kernow was down to the same debate that was occurring in most of the political parties campaigning for autonomy from the United Kingdom at the time ( for example the Scottish National Party and Plaid Cymru ), whether to be a centre-left party appealing to the electorate on a social democratic line, or whether to appeal emotionally on a centre-right cultural line.

The campaign was taken so seriously by Gwynfor Evans, former president of Plaid Cymru, that he threatened the government with a hunger strike were it not to honour the plans.

It was addressed by Labour MPs Jon Trickett, Emily Thornberry, John McDonnell ( politician ) | John McDonnell, Michael Meacher, Diane Abbott and Jeremy Corbyn, and Elfyn Llwyd of Plaid Cymru and Angus MacNeil of the Scottish National Party.
