Batley is one of eight towns mainly bounded by the M62, A653 and the A644. You can drive from one town to the other and not know you left. The area sits to the south and between Leeds and Bradford and also Wakefield, and they are all connected. The area has a population the size of its nearest neighbour, the city of Wakefield, ~ 370,000.
So, it's small, but is it important.
You bet it is.
It is a swing seat, as are most of the other seven towns, and it is currently Labour held on a majority of about 3,500. It will be a barometer of where we are.
