Is the Andrew Marr show biased towards women?

I came across a tweet from Piers Morgan this morning in which he suggested that the BBC is favouring women since 43 out of the 53 paper reviewers on The Andrew Marr Show in 2019 were women. Unfortunately I was a day late to this hot-take, fortunately this is because I don’t follow Piers Morgan. However, I knew that there must be more to it than a single PC-baiting statistic and knowing that I had a ~3 hour train journey coming up this evening I thought I’d look into it a bit more.
