Nigel Coghill-Marshall, who stood in the Berwick constituency at last year’s General Election, said: “This is excellent news.
“Coupled with the fact that Kate Hoey of Labour has taken a leading role in one of the umbrella groups, there is now proof that the campaign to leave the EU is no longer seen as a one-party issue.
“Increasing numbers of politicians from across the political divide now see that the fight against the creation of a federal Europe transcends any minor policy differences that we might hold on other issues.
“I admire those people who have been able to campaign according to their consciences without fear of being disciplined by their party whips. They are putting country first.”
Mr Coghill-Marshall continued: “As someone who began to campaign against this supra-national state in 1968 when I joined the Anti Common Market League because even then, as a teenage Young Conservative, I could see what was planned by the European elite, it encourages me to find, that at long last, the need to restore the UK’s independence as a sovereign nation is accepted across the political spectrum.
“In four months, the future of our nation will be decided. It is important that everyone understands just what is at stake.
“I hope that everyone will listen to the arguments and realise that it is about more than just to whom we can, and cannot, pay benefits.
“It is about more than the interests of multi-national companies. It is about the continued existence of our nation.”
Locally, the campaign has begun. A market stall was held by Vote Leave in Alnwick on Saturday, manned by volunteers from all parties and none.
A stall will be held next month in Berwick with a public meeting planned for April, details of which will be released nearer the time, but speakers will include Anne-Marie Trevelyan MP, Nigel Coghill-Marshall and at least one other regional politician.
