Thin on the right so far
Only 13 of the 36 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Leaders of the Scottish National Party (SNP), Plaid Cymru in Wales, and Sinn Féin in Northern Ireland met in Cardiff on Monday, 14 September 2026. They signed a memorandum of understanding that declared their nations' right to self-determination and called for the UK government to hold referendums on independence for Scotland, Wales, and a united Ireland. The agreement stated that no Westminster government has the right to block democracy or undermine the principle that people will decide their own future. The meeting took place in the wake of US President Donald Trump's public comments supporting Irish unity during a visit to Dublin the preceding weekend.
Disagreement on Trump's role
While several reports noted US President Donald Trump's comments on Irish unity, the Evening Standard reported that he declined to comment on Scottish independence. Other reports did not specify whether Trump commented on Scottish independence or not.
What the coverage left out
None of the centre-rated outlets ran this story. The right-rated reports did not mention the memorandum of understanding's call for referendums on independence for Scotland and Wales, focusing instead on Michelle O'Neill's comments about Irish unification and Donald Trump's remarks.
Still developing. We have re-checked which outlets are covering this 7 times, most recently on 15 Sept 2026, 13:00, and will add the sides that appear.
How other outlets pictured it

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
18 rated outlets
- Seven left-rated reports led on the meeting of the leaders of Sinn Féin, the SNP, and Plaid Cymru and their signing of a memorandum of understanding. These reports highlighted the call for self-determination and independence referendums for Scotland, Wales, and a united Ireland. The timing of the meeting in relation to US President Donald Trump's comments supporting Irish unity was also a prominent feature. ABC Australia, for example, quoted the agreement stating, 'Our nations have the right to self-determination. No Westminster government has the right to block democracy or undermine the principle that our people will decide their own future.' Dnevni list Danas reported that the parties declared the right to self-determination, with the headline stating, 'Our People Will Decide Their Own Future.' Perspectivemedia.com and The Independent also focused on Michelle O’Neill's statement that Trump's comments show the debate is 'very much alive'.
Centre
5 rated outlets
- BBC News led on the statement that Plaid Cymru, SNP and Sinn Féin leaders urged the UK government to prepare for constitutional change. The Economic Times reported that the pact does not itself dissolve the United Kingdom and that Westminster would still need to participate in any Scottish or Welsh independence process.
- Internewscast noted that Donald Trump voiced support for a united Ireland, while RTÉ recorded John Swinney’s prediction that Andy Burnburn will be the United Kingdom’s last prime minister. None of the centre digests mention a cost estimate, a timetable, or the specific text of the signed pact.
Right
13 rated outlets
- Three right-rated reports focused on Northern Ireland First Minister Michelle O’Neill's comments regarding US President Donald Trump's remarks on Irish unification. The Evening Standard's headline stated, 'Trump comments on Irish unity show debate is ‘very much alive’: Michelle O’Neill.' The Nation and Anadolu Ajansı also used similar headlines, highlighting O'Neill's assertion that Irish unification is 'very much on the table.' These reports mentioned the signing of a memorandum of understanding by the leaders of Sinn Féin, SNP, and Plaid Cymru, but the emphasis was on the reaction to Trump's statements and the ongoing debate about Irish unity.
