The former US President praiseed John Hume
Former US President Bill Clinton honoured John Hume during his one-day visit to Northern Ireland.
In a speech at the Guildhall Square in Derry city, the statesman spoke of city native Hume's contribution to peace in Northern Ireland.
SDLP veteran Hume was honoured with former Ulster Unionist leader David Trimble when they were jointly awarded the Nobel Peace Prize in 1998.
The Nobel Laureate was one of the key politicians to successfully broker the peace deal that was the Good Friday Agreement in 1998.
Clinton also visited the University of Ulster's Magee campus while in Derry where he was heckled.
He will then travel to Queen's University in Belfast later in the day where he will officially open the university's new William J Clinton Leadership Institute.
While there, he'll deliver his inaugural speech after he meets with First Minister Peter Robinson and Deputy First Minister Martin McGuinness.
In his speech, he is expected to discuss the challenges currently facing the Stormont Executive after the recent crisis following revelations about On The Runs which led to Peter Robinson threatening to resign.
Ahead of his visit to Queen's University, Clinton said: "I have long tried to support economic development in Northern Ireland and believe preparing young leaders is essential to long term prosperity. So, I am happy to be associated with this institute."
The new vice-chancellor of QUB, Prof Patrick Johnston, said: "We are honoured that President Clinton has given his name to our leadership institute and we are delighted that he has joined us in person to set the seal on that partnership."
