David Trimble - the man who helped set NI on rocky road to devolved government

In a statement on behalf of the Trimble family, the UUP said: “It is with great sadness that the family of Lord Trimble announce that he passed away peacefully earlier today following a short illness.”

He was one of the principal architects of the Belfast Agreement ending decades of conflict in Northern Ireland.

Lord Trimble jointly won the Nobel Peace Prize along with SDLP leader John Hume.

The Co Down man distinguished himself in an academic career in the law faculty at Queen’s University before moving into politics.

He initially became involved in the unionist offshoot organisation Vanguard in the early 1970s and while he was best known for his involvement with the Belfast Agreement, in his younger days he had opposed an earlier attempt, the Sunningdale Agreement.

He went on to join the then dominant UUP in 1978.

It was at the university in 1983 that he heard the IRA’s gunshots which killed his fellow law professor and UUP colleague Edgar Graham.

He left academia for politics full time when he was elected as MP for Upper Bann following a by election in 1990 after the death of the incumbent Harold McCusker.

Lord Trimble rose to prominence partly due to the Drumcree dispute as nationalist residents opposed the procession of an Orange parade along the Garvaghy Road.

He led the parade along the road in 1995, famously joining hands with DUP leader Ian Paisley.

A few months later, Lord Trimble unexpectedly won the leadership of the UUP over the favourite Lord Kilclooney, starting his often turbulent time at the helm of the party.

He marked a number of firsts as UUP leader, including becoming the party’s first leader in 30 years to meet with the Irish premier in Dublin and in 1997 he became the first unionist leader since partition to negotiate with Sinn Fein.

The peace talks, which started formally in 1998 under the chairmanship of former US senator George Mitchell, saw many nights of intensive negotiation pressed on by then prime minister Tony Blair, taoiseach Bertie Ahern and then US president Bill Clinton.

The process faltered several times but perhaps most notably when then Ulster Unionist Jeffrey Donaldson walked out of the talks.

However, on April 10 1998 the agreement was signed, and endorsed following a referendum held the following month.

Lord Trimble become the first first minister of Northern Ireland to be elected on July 1, 1998 alongside SDLP deputy leader Seamus Mallon as deputy first minister.

But the path of devolved government was far from smooth for the two men, with the issue of the paramilitary groups decommissioning overshadowing Stormont.

Lord Trimble also struggled with internal party divisions which saw Mr Donaldson, along with fellow future DUP leader Arlene Foster and Norah Beare, resigning in December 2003.

Lord Trimble lost his Westminster seat in Upper Bann at the 2005 election to DUP candidate David Simpson.

He resigned as leader of the party whose once dominant Westminster representation had been reduced to just one seat.

He was made a life peer the following year and later took up his seat in the House of Lords as a member of the Conservative Party great influence on UK politics.

Lord Trimble’s final public appearance came at the end of June at the unveiling of a portrait of him by artist Colin Davidson at the Queen’s University.

He then reflected on the approach of the 25th anniversary of the Belfast Agreement, and pointed out it has survived despite the objections.

“The Good Friday Agreement is something which everybody in Northern Ireland has been able to agree with, it doesn’t mean they agree with everything, there are aspects which some people thought were a mistake, but the basic thing is that this was agreed,” he told PA.

“That is there.

“People are actually not throwing the agreement to pieces, their complaints are still based on the existence of the agreement.

“They are not saying ‘throw it out’, so that’s the thing to bear in mind.”

Lord Trimble is survived by his wife Daphne and sons and daughters, Richard, Victoria, Nicholas and Sarah.
