Good morning. Back in May, the shape of British politics shifted dramatically. I’ll forgive you if you were too preoccupied refreshing Andrew Sparrow’s live blog for the latest speculation about Keir Starmer to notice, but since 7 May, centre-left nationalist parties that ultimately aspire to leave the UK have been in government for the first time simultaneously in Scotland, Wales and Northern Ireland.
This week sees the initial codification of that shift. In Cardiff yesterday, Plaid Cymru leader Rhun ap Iorwerth, Scottish National party leader John Swinney and Sinn Féin vice-president Michelle O’Neill (who shares power with the Democratic Unionist party) affirmed their countries’ right to seek independence from the UK. Along with the leader of the opposition in Ireland, Mary Lou McDonald, they signed a memorandum of understanding that called on Westminster “to prepare, plan and facilitate constitutional change in Wales, Scotland and Northern Ireland”. And they posed for a fair number of group photos too.
