The Irish premier has said he is confident an agreement between the UK and EU over Brexit can be reached by Wednesday night.
Speaking on Wednesday, Leo Varadkar said he had spoken to Prime Minister Boris Johnson earlier that morning and he is optimistic progress is being made and that a deal could be ratified at the European Council summit on Thursday or Friday.
"There is a pathway to a possible deal but there are many issues that still need to be resolved, particularly around the consent mechanism and issues around customs and VAT," he said.
The Taoiseach continued: "The 31st of October is still a few weeks away and there is a possibility of another summit before that if we need one.
"A lot of things have changed in the last three years, many twists and turns, but what's never changed is our objectives.
"Our objectives are simple ones, avoiding a hard border between north and south, ensuring the all-island economy will continue to thrive and prosper, for north-south cooperation to resume, as envisaged in the Good Friday Agreement, and protect the integrity of the single market.
"Although time is running short I am confident these objectives can be achieved.
"In the mean time, we must continue to make our plans and prepare for no deal, because we have to prepare for the worst case scenario no matter what."
Mr Varadkar will travel to Brussels for the EU summit on Thursday, where negotiators are currently in the "tunnel" stage of negotiations.
