The House of Lords opens up the chamber every year, inviting people from across the UK to take part in a debating event.
2019 Chamber Event: How can we reach a sustainable future?
The 2019 debate focused on climate change and how the government, individuals and industries should tackle the pressing issues we face today, as well as the ethical questions about how our lifestyle choices will impact people in the future.
Subjects up for debate in recent years have included international relations, free speech, social care, climate change and the future of the Lords itself:
