Do you live under a rock? Reeves and Labour have pushed the "Brexit" angle for the last month non stop! Do you actually watch any news or read any?
It isn't sexist. Thats just an oft repeated BS thing that is on TV all the time. It could be Bob from accounts, Dave from accounts or whatever. Its just a swipe at claiming she was some top economist at all these big banks only for it to turn out she was something to do with customer services. Rachel from Customer services doesn't have the ring that accounts does. The whole "misogynist" angle is ridiculous. If the next chancellor, or other high office, claims something similar that turns out to be fake, you can bet your bottom dollar they will get a nickname. Country's gone mad looking for isms in anything these days. People seem to forget these nuggets despite them being very recent: Spreadsheet Phil, Liz the Lettuce, Gideon, 2 Jags, Maybot, Pob, Dishy Richi, Leaky Sue, Kami Kwasi, Keith, Mad Nads, Magic Grandpa, Doris Karloff.
