A very topical issue - and this week the Constitution Unit conducted an online seminar on the subject. It lasts for an hour - and is very informative.
You can subscribe to the Constitution Units Seminar Series videos on Youtube and the Unit itself at https://www.ucl.ac.uk/constitution-unit/ . A Conference on "Johnson's Constitutional Reform Agenda" will be held on 17th & 18th June - further details (spoiler - it is a FREE conference) are available here.
