Surprised at that graphic, it suggests that Samuels is more senior than Secker with the larger font.
Honestly if they are short of staff they can get rid of double headed, which I suspect might happen in the near future.
What a load of laughable rubbish.
Jonathan's name just takes up more room, and to suggest that it's anything to do with his "seniority" enters into the realm of what I'd call "pres fetishism" - the practise of deriving what you want to out of pres elements to the exclusion of all reality just so you get to sound like an insider.
Seriously, do you think some people were sat in a room in Osterley at some point in the last 48 hours and said: "I know Jayne's a longstanding presenter, and Jonathan's only done a couple of overnight shifts in the chair up to now, but his seniority as a correspondent outranks hers as a presenter [which, by the way, it doesn't], so let's show the audience we know that by making his introductory name strap marginally larger than hers"?
I can assure you my colleagues have better things to do.
