Sharing some snaps from her final filming day, she also unveiled her replacement. Dr Anne-Marie Imafidon is a mathematics genius who previously appeared on a “Black To Front” edition of the show.

Rachel also posted earlier this week about preparing for her break from the screen.

She penned: “Last day at work today before mat leave so here’s an artist’s impression of my throat right now. Not long left!”

Following her new update, Rachel was inundated with well wishes from her followers.

Fan Kieran O’Driscoll wrote: “Aw Rachel, you will be very much missed but @aimafidon will certainly be a worthy Keeper of the Numbers till your return next year.
