A pair of twins who claim to be the most identical in the world are calling on the Australian Government to change the law so they can both marry their shared boyfriend.

Anna and Lucy De Cinque, 33, have been dating their mechanic boyfriend Ben Byrne for six years but can't marry him under Australia's anti-polygamy laws.



The Perth pair told Australian TV host Dave Hughes: "Okay, so we share a partner Ben and we would like marry him one day but the law in Australia says we can't, so what do we do?"

The twins shared a promotional video of the interview to their Instagram account with the caption: "We share a unique problem. WE WANT TO MARRY THE SAME MAN."
