Reginald Styles

Sir Reginald Styles was a diplomat who arranged the second World Peace Conference at Auderly House. He was almost assassinated by time-travelling guerillas from an alternate 22nd century in which the conference had been destroyed and global war had broken out as result. They believed that Styles was planning to betray the conference members in an attempt to seize power for himself, but it was in fact their own attempts to prevent it that created their timeline. The Third Doctor saved Styles and the conference was successful. (TV: Day of the Daleks)
