Comic Relief is an operating British charity, founded in 1985 by the comedy scriptwriter Richard Curtis and comedian Lenny Henry in response to famine in Ethiopia. The highlight of Comic Relief's appeal is Red Nose Day, a biennial telethon held in March, alternating with sister project Sport Relief. Comic Relief is one of the two high profile telethon events held in the United Kingdom, the other being Children in Need, held annually in November.

Comic Relief was launched live on Noel Edmonds' Late, Late Breakfast Show on BBC1, on Christmas Day 1985 from a refugee camp in Sudan. The idea for Comic Relief came from the noted charity worker Jane Tewson, who established it as the operating name of Charity Projects, a registered charity in England and Scotland.

The charity states that its aim is to "bring about positive and lasting change in the lives of poor and disadvantaged people, which we believe requires investing in work that addresses people's immediate needs as well as tackling the root causes of poverty and injustice.".

Catherine Tate (born Catherine Ford on 12 May 1968) is an English actress, writer and comedienne. She has won numerous awards for her work on the sketch comedy series The Catherine Tate Show as well as being nominated for an International Emmy Award and seven BAFTA Awards. Following the success of The Catherine Tate Show, Tate played Donna Noble in the 2006 Christmas special of Doctor Who and later reprised her role, becoming the Doctor's companion for the fourth series in 2008. In 2011, she began a recurring role as Nellie Bertram on The Office.

Tate was born in Bloomsbury and brought up in the Brunswick Centre. Her mother, Josephine, was a florist, and Tate has said that the character of Margaret in The Catherine Tate Show, who shrieks at the slightest of disturbances, is based largely on Josephine.

Tate never knew her father, as he left very early on in her life, and consequently, she was brought up in a female-dominated environment, being cared for by her mother, grandmother and her godparents. As a child, Tate suffered from an obsessive-compulsive disorder which centred on word association. For example, Tate was not able to leave a jumper on the floor or it might have brought misfortune to her mother whose name began with the letter "J" like jumper.
