This week on Taking Stock Mandy Johnston looks at the Taoiseach’s bold new idea: a Department of Infrastructure. Does anyone really want another government department? Mandy talks to Economist John Fitzgerald and Conal Thomas of the Business Post. In our monthly Techscape slot we look at the social media platform that is Telegram and ask what really goes on there when Mandy chats to David Stokel-Walker. And the honeymoon is over for Keir Starmer, as the Labour party conference gets swallowed by black holes and the age-old 'who-paid-for-that-shirt' saga. Mark Paul of the Irish Times was there and he tells us all about it.
