The Wycombe MP took the opportunity to have a self-defence class from a local business, Combat Academy, on his day off.
"The guy in the video, Reece Coker, came to see me and told me that when people need purpose in their lives, training in self-defence can really give them self-esteem, so I decided to go along," Baker told MailOnline.
"Self-defence can also help young people channel themselves to give them self-esteem, to use their aggression to do some good," he added.
"We know that in this country we've got all sorts of issues - gang violence for example.
"I think it’s worth having a look at how something like this can change lives."
