Sir Keir Starmer: Taoiseach congratulates new UK prime minister

There has previously been tension at times between London and Dublin in recent years.

The British government’s Legacy Act was opposed not only by the Northern Ireland political parties but also repeatedly by the Irish government.

Its introduction on 1 May meant an an end to historical inquests and the transferring of Troubles-era cases to a new body.

The act’s most controversial element, the offer of conditional immunity to suspects, has been disapplied following legal action by bereaved families.

The court ruled this part of the act was incompatible with human rights’ legislation and the Windsor Framework.

Brexit negotiations also caused some tension on the relationship between London and Dublin.

And, there have been tensions over asylum seekers.

Earlier this year, the Irish government complained of a significant spike in the number of asylum seekers arriving in Ireland from Northern Ireland.

The Irish government argued the UK had a duty to take them back.

But, the then prime minister, Rishi Sunak, ruled that out.
