In the first deconstruction of what will, undoubtedly, be a series:
Myth #7: Wales would be kicked out of the European Union.
Myth Busted: It has been officially confirmed that Wales, if independent, would remain within the European Union. Former Secretary General of the European Commission confirmed this, when discussing the case of Scotland:
"There is no precedent and no provision for the expulsion of a member state, therefore Scottish independence would create two new member states out of one. They would have equal status with each other and with other member states.
The remainder of the United Kingdom would not be in a more powerful position than Scotland…Anyone attacking the claim in respect of one country is attacking the claim in respect of the other. It is not possible to divide the cases." 2
Also, under the principles of the Vienna Convention on the Law of International Treaties, Wales would remain a part of the European Union, as would the other countries of the UK. The Convention states that an international agreement still applies to newly independent countries when a signatory state is broken-up.

OK, let’s indulge in a little bit of evidential rigour here:
1.It’s not been "officially confirmed" that Wales, or indeed Scotland will remain automatically a part of the European Union post-separation. There is no precedent, no guidelines to follow on the matter.
2.The "original" member and signatory state, ie United Kingdom, would obviously not be expelled post separation. Wales would however no longer be a part of that member or signatory state would it?
Would it have to reapply for membership to a body many of whose members have separatist worries of their own?
Nobody knows, there are no precedents nor guidelines in the matter.
3.Opinions have, nevertheless, been expressed on the subject in both directions.
Dr Joe Borg, EU Fisheries Commissioner:
Legally speaking, the continuation of the membership would remain with the rest of the UK - less Scotland. And, therefore, Scotland, as a newly independent state, would have to apply for membership.
My colleague across the North Channel has quite a few more professional opinions opposing the gist of the late Émile Noêl(neither very professional nor courteous for Plaid Cymru to omit his name)’s views.
But basically, the truth is that there are no precedents or guidelines in this matter.
So, Plaid Cymru haven’t done anything like "bursting the myth".
They’ve copy and pasted the SNP line.
And that line can’t be proven one way or the other because there are no, and I’ll say it again for the fourth time, precedents nor guidelines in this matter.
