In the UK, thousands of people are expected to march through central London later today as part of a protest calling for a second Brexit referendum.
The event will be addressed by both senior politicians and celebrities when it concludes outside parliament.
The last demonstration organised by the Peoples Vote group attracted an estimated 700,000 people onto the streets of London demanding another ballot on Brexit.
Organisers hope that today’s attendance could exceed that number as the political chaos around the UK’s departure from the EU continues.
The Deputy Leader of the Labour Party Tom Watson is expected to tell the crowd that he would vote for Mrs May’s deal or a revised deal agreed with Labour – but only if the public has a vote on it too.
The rally will also hear from Scotland’s First Minister, Nicola Sturgeon and London Mayor, Sadiq Khan.
Theresa May is expected to bring her Brexit deal back for a third vote in the House of Commons in the coming days following the EU decision to grant Mrs May extra time on a Brexit deadline which had been due to expire next week.
Meanwhile, the Tánaiste, Simon Coveney, said that the European Commission and both the Irish and British Governments have examined ways of preventing a hard border in Ireland in the event of a no-deal Brexit.
Mr Coveney said while there were conversations there had been no formal discussions and the backstop would form the basis of any such negotiations.
He insisted the focus would remain on regulatory alignment if this scenario were to emerge.
