Cranarch

Lord Cranarch once held a high position in British intelligence and lived at the family home of Repton Abbey were he often entertained guests for dinner including the Doctor. On one such occasion his household was invaded by aliens led by Lord Ryzt and had their memories drained in order to further a bigger invasion of the country. An invasion was thwarted when the Doctor used the alien technology to hypnotise them into thinking that the planet wasn’t worth the effort and that they should go home. With the aliens gone the Doctor and his companions stayed for dinner. (DWA: The Demons of Repton Abbey)
