Tanaiste Simon Coveney says peace is the biggest single achievement we share with Britain.
In an editorial for the U.K. edition of today's Sunday Times, Minister Coveney says the British and Irish Governments have a shared obligation to protect the Good Friday Agreement and says the Withdrawal Agreement is not up for renegotiation.
Simon Coveney says Ireland has had one red line since Brexit was a concept and nothing should be done to put peace at risk.
He says the Government will work closely with the new British Prime Minster, adding that it has a fundamental interest in a successful, prosperous UK.
However, while the personality in Downing Street will change this week, he says the facts and complexity relating to Brexit remain the same.
The Tanaiste says there will be huge damage to all if Britain decides to leave without a deal, adding that it's important to be honest about the impact of decisions on people who have not chosen to leave the EU.
He says the withdrawal agreement is a balanced document dealing with the interests of all parties and it's not up for renegotiation.
