"A teacher who sexually abused two pupils at South Lanarkshire secondary schools has been jailed for six years."
"The 60-year-old, from East Kilbride, was also convicted of sexually assaulting a 13-year-old boy in 2014."
"At the High Court in Glasgow, a judge told now-retired Burton that he had acted `disgracefully` towards the boys."
"Lady Stacey told him: `You abused the trust that the children had in you`."
"Burton, who maintains his innocence, showed no emotion as he was led handcuffed to the cells."
"His lawyer said he had been a `gifted` teacher, but that his reputation now `lay in tatters`."
"The court was previously told that Burton had taught maths and had been an assistant principal teacher."
"The jury heard that he got to know the first victim around 1994 when he was in first year and later went on to abuse him."
"The abuse ended when the boy was around 15."
