Rachel Riley REPLACED on Countdown by YouTube star in major show shake up
RACHEL Riley has been replaced on Countdown in a shock move - and by a YouTube star.
The Channel 4 questions and numbers show will undergo its biggest shakeup in recent years.
Rachel, 39, will temporarily step away from the daytime hit to focus on another project.
Countdown producers have drafted in mathematician Dr Tom Crawford as her replacement.
Dr Crawford appears more than qualified for the role, having obtained a PhD in Fluid Dynamics from the University of Cambridge.
The YouTuber also completed a maths degree from the University of Oxford.

Speaking about joining the show, he said: "COUNTDOWN. Still can’t believe this happened, but you will now be able to watch me attempting to do maths live on television for the next 3 weeks, starting Monday at 2:10pm on @channel4. @rachelrileyrr - and her unparalleled arithmetic skills - are irreplaceable, but with @mrcolinmurray and @susiedent by my side, we’ll do our very best to keep you entertained for the next few weeks.
"Long live daytime television!!"
Rachel joined Countdown in 2009, having taken over from Carol Vorderman who departed in 2008.
