Varadkar to deliver address to UN in New York
Mr Varadkar will speak at the Nelson Mandela Peace Summit at the UN, which Ireland worked in partnership with South Africa to organise.
In his address, Mr Varadkar is expected to reference the Northern Ireland peace process and highlight the fact that this year marks the 20th anniversary of the Good Friday Agreement.
Today's summit is part of the United Nations General Assembly and the Taoiseach will use the opportunity to meet world leaders and UN officials to promote Ireland's bid for a seat on the United Nations Security Council.
US President Donald Trump will also be at the UN to attend a meeting on tackling the illegal drugs trade.
Mr Trump is due to address the United Nations General Assembly tomorrow.
Speaking ahead of the summit, the Taoiseach said the event marks an important opportunity to reflect on Nelson Mandela’s legacy.
"It’s not only a celebration of his life, but also a moment for the global community to see how Mandela’s commitment to peace, reconciliation and human rights, can help us to meet the challenges we face today," he said.
