was a
Parliamentary Constituency in the British
House Of Commons .
The constituency was formed from the constituencies of
Fermanagh North ,
Fermanagh South ,
Tyrone North-East ,
Tyrone North-West and
Tyrone South . It covered
County Fermanagh and
County Tyrone in
Northern Ireland , within which it was the only constituency to regularly elect Nationalist MPs. It was abolished in
1950 . Much of the constituency then became
Fermanagh And South Tyrone , the remainder part of
Mid Ulster .
Nationalist MPs were elected in every general election and by-election held in the constituency, except for the
1924 UK General Election , when no Nationalist stood and two Ulster Unionists defeated two
Sinn Fein candidates.
