Sinn Féin vice president Michelle O'Neill’s acceptance of the offer to attend the coronation of King Charles III may come a surprise to some. It is standard protocol for such an invitation to be made to all significant political parties in the UK, including those in the devolved regions, and Sinn Féin is now the largest party in the Northern Ireland Assembly. However, history is a complicating factor in this case, and even today Sinn Féin still refuses to take its seats in the Westminster parliament. This is an expression of its refusal to recognise British sovereignty over Northern Ireland.
Sinn Féin will argue that attending Charles’s coronation is merely a mark of respectful neighbourly relations rather than any act of fidelity. It is, of course, also a gesture to Ulster unionists. Indeed, on announcing her intention to attend the event, O'Neill said as much, declaring that it was “time to respect our differing and equally legitimate aspirations” in Northern Ireland. While still emphasising her own republicanism, she also recognised that “there are many people on our island for whom the coronation is a hugely important occasion”.
