Former prime minister Gordon Brown told Sky News he was too old to be a politician in the UK but too young to be one in the US. He has a point, with Americans set to choose between 81-year-old Joe Biden or 77-year-old Donald Trump in November's presidential election, while here in Europe, France's new prime minister is 34-year-old Gabriel Attal. On the Sky News Daily, host Niall Paterson explores whether there is a perfect age for our politicians. He talks to Labour's Harriet Harman, who is the longest-serving woman MP and 'Mother of the House of Commons'. The 73-year-old representative for Camberwell and Peckham has been an MP for more than 40 years. Niall also speaks to Amy Callaghan, SNP MP for East Dunbartonshire, who was elected in 2019 aged 27. They discuss what makes a good MP, the challenges women MPs face when elected, and if age in politics is just a number.
