David Trimble entered politics in 1975, representing South Belfast on behalf of the Vanguard Unionist Party in the Northern Ireland Convention until 1976.
In 1996, he led the UUP negotiating team into another round of talks arranged by the United Kingdom and Irish governments, in a bid to end 30 years of sectarian violence – ‘The Troubles’ – in Northern Ireland. These talks eventually proved successful, and the Belfast Agreement (better known as the ‘Good Friday Agreement’) was concluded at Castle Buildings, Stormont on Friday, 10 April 1998.
In 1990, Mr Trimble was elected MP at Westminster for Upper Bann Constituency. He was elected Leader of the Ulster Unionist Party on 8 September 1995, and went on to be elected First Minister in the new Northern Ireland Assembly in 1998.
