Blue Peter presenters deliver message about racism
Hacker T Dog, a popular CBBC puppet for over 16 years, will joinBlue Peter as a new presenter from September.
He will become the 44th presenter of the world's longest-running children's TV show, appearing regularly in the studio.
To mark his debut, Hacker T Dog will take viewers on a special tour of his hometown, Wigan.
Blue Peter will also introduce a new look and format, relocating to Campfield Facilities at Versa Studios in Manchester.
The show will cease future live episodes due to changing viewing habits, though the Blue Peter Garden and RHS Bridgewater garden will still be used for filming.
