Category: Ultra-marginal Conservative seat

Geography: Yorkshire and the Humber, West Yorkshire. Part of the Wakefield council area and part of the Leeds council area.

Main population centres: Morley, Outwood, East Ardsley, Wrenthorpe.

Profile: A pair of small towns between Leeds and Wakefield, both former industrial towns turned into residential dormitories. Morley was once a textile and coal mining town, now a hub for new housing development. Outwood was a former pit village, but has seen a massive expansion of new build housing over the last few decades. The area is also, perhaps somewhat incongrously in this post-industrial landscape, a centre for growing forced rhubarb. The area between Morley, Rothwell and Wakefield has for centuries been the centre for rhubarb growing and in 2010 won Protected Designation of Origin status.

Politics: Morley and Outwood was previously the seat of Ed Balls, Gordon Brown's ally and the Labour shadow Chancellor under Ed Miliband. After boundary changes in 2010 the Tories ran an energetic campaign hoping to defeat Ed Balls and provide a "Portillo moment" of the election, but fell tantalising short. In 2015 the situation was the opposite, no one expected a Tory victory here given the polls were pointing to Labour gains, but Balls was the most high profile casualty of the surprise Conservative victory.
