Bill Clinton greets those who came to hear his speech

Earlier, socialist protesters threw eggs at Mr Clinton as he visited the University of Ulster's Magee campus.

During his visit to the Magee campus, Mr Clinton met the leaders of the four main churches.

The Church of Ireland Bishop James Mehaffey said the former president had made a tremendous contribution to Northern Ireland.

Mr Clinton was accompanied by his daughter Chelsea on his visit to the city.

Later, he attended a private dinner hosted by the Londonderry Chamber of Commerce.

Bomb site peace centre

Meanwhile, it has been confirmed that a peace centre is to be built in honour of Mr Clinton in Enniskillen, County Fermanagh.

Eleven people died in the Enniskillen bomb

The William Jefferson Clinton International Peace Centre is to be based at the Higher Bridges project building on the site of the 1987 IRA Remembrance Day bomb.

The centre will focus on peace-building in Ireland and overseas and will cement a long-term relationship between Mr Clinton and the province.

It is hoped the centre will also stimulate social and economic regeneration in Fermanagh.

Mr Clinton is to meet relatives of the 11 people killed and some of those injured in the Enniskillen bomb, when he travels to the town as part of his itinerary on Thursday.

He will also meet Fermanagh district councillors, church representatives and members of the Fermanagh University Partnership Board and unveil a window inscription for the peace centre.

Reconciliation fund

On Tuesday evening the ex-president addressed a gala centre in Dublin.

He was joined at the event by Irish Prime Minister Bertie Ahern who announced that his government is to establish a centre for American studies in honour of Mr Clinton.

Mr Ahern said the Irish government would contribute IR�2.5m towards the cost of building the centre and a further IR�200,000 in annual running costs.

Ex-senator George Mitchell attended the dinner

Guests at Tuesday's gala dinner, which also included former US envoy to the province, ex-senator George Mitchell, were believed to have paid up to IR�10,000 for their seats at Dublin Castle.

The event has raised about IR�700,000 for the Northern Ireland Fund for Reconciliation.

Prominent Irish businessman Noel Smyth, head of the event's organising committee, said it was a "wonderful opportunity to honour Mr Clinton for his enormous contribution to fostering peace in Ireland".

The reconciliation fund was established two years ago by Mr Mitchell, together with the leaders of the political parties which supported the Good Friday Agreement.
