William "Billy" Longknife was Kris Longknife's father and was the prime minister of Wardhaven. After the murder of Edward Longknife, Kris almost never saw her father. She learned later that he had ordered her soccer games recorded so he could watch them. William was upset when Kris joined the Navy.
William lost a vote of confidence in the Wardhaven Parliament and fought to regain his position, beginning with offering to form a government of national unity with his successor after unidentified warships entered the Wardhaven system.
