Comprising the 56 parliamentary constituencies in the counties of North Yorkshire, South Yorkshire and West Yorkshire together with the unitary authorities of Kingston upon Hull, East Riding of Yorkshire, North East Lincolnshire, North Lincolnshire and York.
At the 1997 general election Labour won 47 seats, the Conservatives 7 and the Liberal Democrats 2.
Labour won more than three-quarters of the seats in the Yorkshire and the Humber region in 1997 with less than 52% of the vote. The Conservative vote at that election declined by less than 10 percentage points compared with 1992 - the party's 'best' performance in England.
Support for the Liberal Democrats was almost unchanged, but they did manage to gain 2 seats from the Conservatives. In both of them (Harrogate and Knaresborough, and Sheffield Hallam) their success, unusually, was boosted by a decline in the Labour vote.
