University Challenge S49E33 Wolfson, Oxford v Durham 

It's a trace of some British accents: add an R after a final A when the next word begins with a vowel.

@@rodrigomarinho1807 So why pronounce Kafkaesque as Kafkaresque?

@@rodrigomarinho1807 also there's no accent involved. It's just lazy, bad diction, or maybe an attempt to sound posh!

@@michaelmccarthy9411 It is accent. I've heard many British people speak like this. And many famous ones also.

@@michaelmccarthy9411 because it's one single word.
