Arlene Foster’s “blood red line” of an Irish Sea border may be a bitter pill for the DUP to swallow, but it is not something entirely new.

It’s 20 years since the Good Friday Agreement established imperfect peace. Hard Brexiters who question the pact are undermining it.

Irish deputy prime minister says his country wants to be UK’s “closest friend” but warns of “hard choices” ahead.

What if Brextremists decided only way to get hard border for Britain was to accept sea border and abandon their allies in Ulster?

The PM’s delicate house of cards has been blasted by DUP. Time to face facts: a workable deal cannot be negotiated as Irish tensions boil.

Leo Varadkar denies being in hurry to unite Ireland politically. But the PM is playing clever game to keep it united economically.

It’s not just DUP whose revolutionary Brexit zeal limits May’s room for manoeuvre; Sinn Fein’s stances restrict Varadkar’s freedom too.

To avoid hard border, May will have to accept lots of EU rules for all the UK or see Northern Ireland become semi-detached from Britain.

New Irish taoiseach deftly deflates UK hopes for an invisible, high-tech inter-Irish border.

The two main parties in Northern Ireland are once more locked in stalemate. But they may find common cause to limit the damage from Brexit.

In most seats, SDLP is the natural choice. But in one, they may back the Alliance Party and in another the official Unionists.

Irish nationalist party is making huge political capital out of Brexit, which DUP backed but most voters in Northern Ireland rejected.
