Comic Relief

7.00 - 8.00:
Lenny Henry kicks off the biggest night in television, this year celebrating 25 years on our screens. Dermot O'Leary and Claudia Winkleman join him to present a first hour absolutely stuffed with contributions from the best comedy and entertainment talent in the UK. Jessie J shaves her head live in the studio, One Direction perform their smash hit Comic Relief single, Miranda Hart stars in a unique (or in her words, 'ruined') edition of Call the Midwife, and Miss Piggy graces us with her presence in the studio.

8.00 - 9.30:
Michael McIntyre and Rob Brydon take over the reins. Highlights include the culmination of another special Comic Relief storyline in EastEnders, Lenny Henry meets the surviving celebrities from this year's extraordinary Zambezi River challenge, Jack Whitehall and Micky Flanagan 'cook off' for Dame Edna Everage in MasterChef, Peter Kay presents the results of his very own physical challenge - something to match anything achieved for the charity by the Zambezi team.

9.30 - 10.30:
John Bishop and Davina McCall pick up the presenting baton as the excitement builds towards one of the most hotly anticipated comic events of the night: Ricky Gervais in a cheap suit - David Brent is back on the BBC. Other key highlights running up to the news are a Comic Relief first from the new queen of comedy Mrs Brown, whilst in the studio Miranda Hart comples the final leg of 'Miranda's Mad March' around the country, joined live by Dawn French and Jennifer Saunders.

The packed night of comedy and entertainment continues as Jonathan Ross and Jack Whitehall are entrusted with BBC Two's previously spotless reputation.

David Brent and Mrs Brown return for more classic comedy and the cast of Fresh Meat go back to their roots with a unique university-based challenge. Plus, a look back at the best moments from this year's Great Comic Relief Bake Off, as Jack and Jonathan possibly attempt to ice a cake - live.

11.00 - 11.45:
Jonathan Ross and Jack Whitehall continue in the hot seat as they find themselves promoted to the flagship channel for good behaviour, where they're joined in the studio by everyone's favourite ex-Doctor, David Tennant. Citizen Khan travels down from Birmingham to be with us, and we premiere another Comic Relief spectacular courtesy of David Walliams, in which we meet all the celebrities that he's been 'intimate' with over the last 12 months.

11.45 - 12.45:
The fun keeps coming as presenters Alan Carr and David Walliams team up to steer us through a suitably irreverent hour. Peter Kay introduces a very special pop promo from his recent Comic Relief challenge, featuring his usual staggering array of willing celebrities, Magician Impossible Dynamo attempts a hugely ambitious illusion from the heart of BBC Television Centre, Russell Howard serves up some especially Good News, and we relive the very best bits from Graham Norton's recent marathon chat show on BBC Three.

12.45 - 01.30:
Russell Brand caps off a stellar line up of presenting talent live in the studio, here to introduce (amongst other things) highlights from his sellout Give It Up for Comic Relief concert. Those just getting in from the pub will have a chance to catch the culmination of Ricky Gervais' extraordinary David Brent sketch, as well as all the other best bits from what promises to be a truly extraordinary night of TV.

Man of the moment Nick Grimshaw enjoys a rare late night as he hosts the now legendary Comic Relief clip show in Grimmy's Comic Relief Late Nighter, featuring the very best sketches from the last 25 years of the telethon, mixed with his favourite comedy clips from the last 12 months. Burning the late night oil with him will be Citizen Khan and special guests.

Highlights from Red Nose Day 2013, this year celebrating 25 years on our screens, with contributions from the best comedy and entertainment talent in the UK.

Lenny Henry, Steve Jones and Zoe Ball look back at an almighty night of comedy and fundraising in this special programme showcasing the best of Red Nose Day 2013, featuring comedy royalty Peter Kay, David Walliams, Miranda Hart and David Brent.

Jack Dee, Dara O Briain and John Bishop also report on how this year's incredible total of over 100 million pounds has been spent across Africa and the UK, while some local fundraisers are treated to a surprise thank-you.
