There are political parties such as Sinn Féin in Westminster which are operationally headquartered in the Republic of Ireland. Also the SDLP is quite Ireland aligned, but is Northern Irish.
Also, Ireland isn’t a foreign country to the UK. It’s independent, but it’s rare that a distinction is made. You don’t need a passport to get from the UK to Ireland and there’s no passport checks either. There may be mild customs check if you are coming from England, Scotland or Wales, but that’s only since Brexit and rare anyway.
