The mum of a schoolboy who missed seven months of school has accused the council of "mind-boggling ineptitude".
James Yalçın was rejected by local secondary schools for the majority of the school year and is only able to get two hours of teaching a day due to the error.
Mum Sarah Yalçın from East London says the 12-year-old has become "depressed" stuck at home without any contact with other children.
