Three Warwickshire councillors accused of making offensive comments about children with special educational needs have apologised.
The remarks included the claim some children were "just really badly behaved", and parents were swapping diagnosis tips on social media.
The council is investigating complaints about the comments made at a meeting about special needs support last month.
Warwickshire County Council said it "acknowledges the scale of the upset".
The three councillors at the centre of the controversy are Conservatives Jeff Morgan, Brian Hammersley and Clare Golby.
