Aubrey Fairchild (The Next Doctor)

You may be looking for the British Prime Minister.

Aubrey Fairchild was a man who worked for several children's charities in the 19th century. He was killed by the Cybermen to gather all the workhouse managers at his funeral where they could be quickly dispatched by the Cybermen. His body was found with burns to the forehead, most likely a result of a Cyberman's Electro Attack. (DW: The Next Doctor)
