The most extensive trial yet of a four day working week is now under way in the UK. More than 3,000 workers at 70 companies will work a day less without having to increase hours over the four remaining days. Edward Siegel is chief executive of Charity Bank, which is taking part in the trial, and tells us why he signed the organisation up. And we hear about some of the possible problems that might be encountered from Abigail Marks, professor of the future of work at Newcastle University. Also in the programme, negotiators from almost 200 countries are meeting in Bonn in Germany for talks to inspire fresh action on tackling climate change. Eddy Perez of campaign group Climate Action Network Canada is one of the attendees, and discusses the mood at the gathering. The budget airline Ryanair is facing criticism in South Africa, where it has been requiring South African nationals to take a test in Afrikaans, amid concerns about the high number of fake passports circulating in the country. The BBC's Nomsa Maseko explains why the move has led to accusations of racial discrimination. Plus, the BBC's Clare Williamson reports on concerns that some older people are getting left behind as banks close branches and move online.

Today's edition is presented by Mike Johnson, and produced by Nisha Patel, George Thomas and Gabriele Shaw.
