behind me will have my full support." In March 1973, the Ulster Vanguard became the Vanguard Unionist Progressive Party. The Vanguard Unionists under Craig formed part of the United Ulster Unionist Council which opposed the power-sharing Sunningdale Agreement. Craig was elected to the Northern Ireland Assembly created under the Sunningdale Agreement, and he won a seat in the UK Parliament at the February 1974 general election for East Belfast. However, in the Northern Ireland Constitutional Convention in the mid-1970s, Craig broke with the majority of his party to support voluntary power-sharing with the Social Democratic and Labour Party. The Vanguard Unionists fell apart, with one section forming the United Ulster Unionist Party, and Craig led the remains of Vanguard to rejoin the Ulster Unionist Party in 1978, but lost his seat at the 1979 general election. Craig subsequently broke with the Ulster Unionists once more. When elections were held for the new Northern Ireland Assembly in 1982, Craig revived the name Vanguard for his candidacy in East Belfast. However, he failed to be elected. That marked the effective end of Craig's political career. After a long period away from public life, he died on 25 April 2011. He had suffered a stroke the previous month. Many historians have agreed that Craig found it difficult to accept that Northern Ireland had to make social and economic reforms. Craig led opposition to those proposals throughout the premiership of Terence O'Neill, James Chichester-Clark and Brian Faulkner. Although he showed few intentions when he became the leader of the Unionist Vanguard movement, he showed public intention to form a Northern Ireland Executive in 1975 with the Social Democratic and Labour Party, along with the Alliance Party and Ulster Unionist Party. That is mainly overshadowed due to his early political beliefs and refusal to accept reform and change to Northern Irish society.
