We are living in troubling times when Emmanuel Macron and his wife, Brigitte, feel they have to go to court to prove she is a woman. The couple's lawyer says 'a line has been crossed' by an online influencer who has repeatedly claimed Mrs Macron is a man.

This week, David Yelland and Simon Lewis look at the 'fight for truth'. Famous people and businesses used to be able to ignore or not comment on stories that were clearly untrue. But in the disinformation age, lies gain traction - and stick - faster than ever. So what are the PR challenges and risks of taking a stand when people have already made up their minds?

And on the extended edition on BBC Sounds, David and Simon look at arguably the toughest PR job in the country - the Archbishop of Canterbury. An announcement on who'll take up the position is expected in the next few weeks - and they face a huge challenge. They'll have a guaranteed platform, but what's the message? At a time when church leaders have written an open letter criticising the 'misuse' of Christian symbols during a march organised by the Far Right, is being controversial unavoidable?

Also, who's up and who's down? Yes, it's league table PR. As Oxford and Cambridge slip down the list of best universities, what dark arts are at play in similar lists? Can they be manipulated - and what are the real reputational risks of falling down the rankings?
