England’s Prime Minister David Cameron welcomed President Michael D. Higgins to his residence at Number 10 Downing Street on the second day of President Higgins' historic state visit to Britain, adding that both countries have become "deep friends."

President Higgins told Cameron that the strength of the relationship between Ireland and Britain is evident in our strong trade and economic links.

The British Prime minister said, "I am really excited by the things that we are now doing together, two countries and two governments. I am excited by some of the new projects that we are talking about.

"But we must, as you said last night and Her Majesty said last night, keep on with the work of reconciliation, including in Northern Ireland. It is wonderful the visit that you are making, it builds on Her Majesty's excellent and remarkable visit of three years ago," he added.

Higgins said that he believes that the short distance between Ireland and Britain has "sometimes stopped us from seeing the richness in each other."

Cameron said the visit built on the queen’s “excellent and remarkable visit” to Ireland three years ago.

“It is a real privilege to be Prime Minister of the United Kingdom at a time when Anglo-Irish relations are on such an up.

“I am determined to do what I can and I know that the Taoiseach is as well to do what we can to play our part in building this very special partnership between two countries that are now not just neighbors, but really good friends and deep friends.”

President Higgins said he was “absolutely delighted to be here and to be making this historic visit,” saying that Anglo-Irish relations are enjoying “ a great deepening kind of cooperation that is very important. It is obviously there in trade and the economy.”
