In a one-hour live special, CBBC's flagship programme is set to remind the nation how it has come to transcend six decades and countless generations and why it still manages to inspire kids to send in more than 100,000 letters and pictures each year with nearly 200,000 under 16s owning at least one Blue Peter badge.

The special diamond anniversary programme will encapsulate all that has made the show unique over the past 60 years.

Past presenters will be joining the celebrations including Valerie Singleton, Peter Purves, Anthea Turner, Konnie Huq and Tim Vincent, some of who have been saving their washing up liquid bottles and toilet rolls for a live studio ‘make' with a difference; Ed Sheeran will be honoured with the highest Blue Peter accolade, a Gold Blue Peter badge; there will be music from Jonas Blue feat. HRVY, The Vamps, and Sophie Ellis-Bextor all accompanied by the BBC Philharmonic Orchestra; the Diamond Time Capsule will be sealed in The National Archives which, as a non-governmental record, is a very rare event; and there will be an announcement about the return of the show's hugely successful Bring and Buy Sales campaign in support of BBC Children in Need this November.

We bring back Blue Peter's bring-and-buy sales and we show you how to put on the perfect one for Children in Need. Lindsey starts her latest physical endurance challenge - Swim Run, also some master UK speedcubers will be showing off their skills in the studio and putting the presenters to the test.
