Baker will leave the show at the end of the series later this month but has two BBC projects in the pipeline. First, he is taking part in Evacuation, a CBBC documentary reality show in which a group of children experience a mock evacuation from their homes to a farm to experience life as it would have been in the Forties.
Also on the cards is Sport's Relief's Only Fools On Horses and presenting at the Blue Peter Prom in July.
Matt, who has presented over 700 programmes since he started in 1999, won the BAFTA as Best Children's Presenter two years running in 2003 and 2004.
He said of his departure: "It was a really tough decision because I love Blue Peter so much. There is no other job quite like it.
"I have spent seven incredibly busy and happy years on the programme but I'm an all-or-nothing person and I think that now is the time to try some different challenges. I'd hate to get stale on a show I feel so strongly about."
"Matt is one of the all-time great Blue Peter presenters, added the show's editor, Richard Mason. "His warmth, courage and personality come right through the screen and audiences recognise the genuine article when they see it. He has worked incredibly hard throughout his long stint on the show and although we're all going to miss him, no-one could say he hasn't seized every single opportunity we've given him.
The presenter's last show will be broadcast on Monday, June 26. His sheepdog, Meg, will leave the show with him.
