1950–1983: The Urban Districts of Cookstown, Omagh, and Strabane, the Rural Districts of Castlederg, Cookstown, Magherafelt, and Strabane, and that part of the Rural District of Omagh not contained within the constituency of Fermanagh and South Tyrone.
The constituency was created in 1950 when the old two-seat constituency of Fermanagh and Tyrone was abolished as part of the final move to single-member seats. Originally, the seat primarily consisted of the northern, eastern and western parts of County Tyrone, with the south included in Fermanagh and South Tyrone. Of the post-1973 districts, it contained all of Omagh and Cookstown and part of Strabane and Magherafelt.
In boundary changes proposed by a review in 1995, the seat was split in two, with the name retained by the eastern half, even though it contained only 30% of the old seat. The western half became the nucleus of the new West Tyrone constituency. The new Mid Ulster also gained areas from East Londonderry and Fermanagh and South Tyrone, taking it deeper into County Londonderry.
In both its incarnations, Mid Ulster has seen a precarious balance between unionist and Irish nationalist voters, although in recent years the nationalists have advanced significantly to be in a clear majority. Many elections have seen a candidate from one side triumph due to candidates from the other side splitting the vote.
In a by-election in 1969, the seat was won by Bernadette Devlin standing as an independent socialist nationalist on the "Unity" ticket, which sought to unite nationalist voters behind a single candidate. At the age of 21, Devlin was the youngest person ever elected to the House of Commons in the era of universal suffrage. The by-election saw a 91.5% turnout, a record for any UK by-election.
Dunlop held his seat for the next nine years, though in 1975 he was part of a large section of Vanguard that broke away to form the short-lived United Ulster Unionist Party. He held his seat in 1979 only owing to a unionist pact. He polled poorly in the 1982 Assembly election, taking 2.8% of the vote. Consequently, he did not stand again in 1983, and the following year the UUUP was wound up.
The 1983 general election saw a fierce contest for the seat, with the UUP, DUP, SDLP and Sinn Féin all polling strongly. The winner was the DUP's William McCrea, by a narrow majority of just 78 over Sinn Féin's Danny Morrison. In general elections from then to 2005 the UUP did not contest the seat.
Following the boundary changes, McCrea contested the new Mid Ulster in 1997 but, by then, Sinn Féin had established itself as the most likely party to outpoll a unionist and so drew votes from the SDLP, resulting in Martin McGuinness winning. He held the seat at the general elections of 2001, 2005 and 2010. During the 2001 general election, Mid Ulster had the highest turnout in any constituency in the United Kingdom.
On 11 June 2012, McGuinness announced his intention to resign from the House of Commons to concentrate on his position as Deputy First Minister and avoid so-called 'double jobbing' by which members of the Northern Ireland Assembly also work as councillors or MPs.[1][2] This necessitated a by-election.[3] On 30 December 2012, Martin McGuinness formally announced he would resign his Westminster seat with immediate effect. Sinn Féin's Francie Molloy won the resulting by-election in March 2013.[4]

Between 1992 and 1996 there were significant boundary changes, creating the new seat of West Tyrone. This had a huge knock on effect on Mid Ulster, which lost all its areas in Omagh and Strabane district councils, and gained the Torrent LGD in Dungannon from Fermanagh and South Tyrone, and the parts of Magherafelt District Council previously in East Londonderry. Therefore, the implied 1992 election results are very different from the actual ones and are displayed above.
The seat was awarded to Beattie on petition on the grounds that Mitchell's conviction as a felon made him ineligible to sit in Parliament. However, Beattie in turn was also found ineligible to sit due to holding an office of profit under the crown, triggering a further by-election.
Mitchell was subsequently unseated by a resolution of the House of Commons, on the grounds that his terrorist convictions made him ineligible to sit in Parliament.[27]
^MPs cannot technically resign. Rather, they can request to be formally appointed to an office of profit, thereby vacating the seat. Sinn Féin, however, rejects elements of this process. The previous case of a Sinn Féin MP resigning was that of Gerry Adams, who simply resigned and Parliament operationalised his resignation by appointing him to an office of profit.
