Welcome to Prime Factors where we review each UK Prime Minister from Robert Walpole to Keir Starmer. We discuss their biography, highs and lows, and then rate them on a scale designed by a 10-year old before awarding the ultimate prize: Are they ”Known” or an ”Ice Cream Cone”? Some dads build a treehouse with their kid. We’re doing a history podcast.
