Elon Musk and the man who wants to take on Trump

We'll be looking at sex, lies and Downing Street later in this episode with a writer who worked in Number10 - and we'll be asking if politicians REALLY want an honest conversation about Immigration - but we begin with the newest launch failure by Elon Musk.

This one involved not a rocket but a presidential candidate - who thinks he can beat Donald Trump.

If that was ever true, it feels much more unlikely today after the campaign launch went up in flames.
