Here's South Basildon and East Thurrock MP Stephen Metcalfe growing into "Movember".
The Conservative MP said: "Men’s health is a cause I am passionate about but in order to make a difference I need your help.
"My commitment is to grow a moustache for the month of November and, in doing so, raise vital awareness and funds for men’s health including prostate and testicular cancer.
"I am asking you to help support my personal journey by making a donation. The size of which isn’t important, every little contribution helps Movember to continue its funding of world class programmes."
Movember aims to highlight and raise funds to battle cancer throughout the month. To make a donation click here.
