Man charged for head-butting former Australian Prime Minister Tony Abbott

Police say a 38-year-old man has been charged with head-butting former Australian Prime Minister Tony Abbott.

Mr Abbott alleged a same-sex marriage campaigner assaulted him on Thursday after asking to shake his hand as he left a newspaper office in Hobart, Tasmania.

The politician is a prominent opponent of same-sex marriage, which is being voted on by Australians at the moment.
