More or Less: Behind the Stats - Social housing, NHS workforce and Liz Truss debt claims

Long: Housing minister Rachel Maclean claimed the government has built a record number of social rent homes. Tim and the team investigate. Following Lucy Letby?s conviction, we look at how sentences for murder have changed over the past few decades. Plus after Liz Truss?s speech this week defending her short stint as Prime Minister, Tim reminds us how her mini-budget raised borrowing costs and might have pushed up the national debt even more.
