The Next Step, CBBC's dire acquisition from Canada, returns to our screens on Wednesday afternoon at 5.30pm. Backers of the mockumentary, as well as its creator/writer, Frank van Keekan, have declined to answer any questions about diversity in the current or future episodes. Newsround Blog readers may recall one episode in which some of the characters are seen laughing at the "funny" British accent.

A somewhat more worthy children's series starts on Wednesday at 5.55pm. Unlike The Next Step, CBBC's documentary, Our School, is real and unscripted. It follows a group of children, in 2013, as they stepped up from various primary schools to their new secondary school, Conyers School in Yarm, Stockton-on-Tees. The first episode of Our School was originally broadcast last week but is being re-screened, and is on the iPlayer. Conyers allowed CBBC to rig the school with "loads of cameras" in the classrooms, corridors and the playground:
