After the Whigs became subsumed into the Liberal party, did the label survive in the House of Lords? As of today, the longest serving current peer began his tenure during the Second World War. It seems reasonable that the Whigs could have survived as a faction into the twentieth century. Was there any peer who thought of himself as a Whig by, say, 1920?
Since there's new interest in this question, I'll refine it slightly. When was the last person who identified himself as a Whig rather than a Liberal, Conservative or Liberal Unionist in the House of Lords?
