Grantham is a small market town in Kesteven, Lincolnshire of about 35,000 inhabitants. Situated on the river Witham, it has the main east coast railway line and the A1 main road from London to Edinburgh running through it. The main local landmark is the impressive parish church of St. Wulframs, which has one of the highest spires found among English churches.

Two world famous people are associated with the town: Sir Isaac Newton, who was schooled at the still existing Grantham King's Grammar School, and Baroness Margaret Thatcher who was educated at King's sister school, Kesteven and Grantham Girls Grammar School (K.G.G.S), and was born in the town itself where many inhabitants still remember her.

Politically the town is part of the Grantham and Stamford constituency (recently altered), is represented in Parliament by Conservative M.P. Quentin Davies and has a long history of electing Conservative members of Parliament.
