Sheffield MP Clive Betts backed an event to help people living with autism and their families.
The Labour politician, who represents Sheffield South East, attended a meeting organised by the National Autistic Society.
The event was one of many taking place around the country as part of a scheme encouraging people with autism to campaign and make more use of local and national media to highlight problems they face.
Mr Betts said: “I was happy to provide insight into the way politics works and who people should be approaching to get their voices heard.”
Eleanor Thompson, a senior officer with the National Autistic Society, who organised the training, said: “Too many people are not getting support.”
