"Under Section 66 of the Representation of the People's Act it is a criminal offence to communicate information about the way someone has voted or is about to vote - or to communicate the unique identification number on the ballot paper."
"But John Turner, chief executive of the Association of Electoral Administrators, said the law was not clear and needed to be updated for the 21st Century."
""We are all up to our knees in the mire trying to work out what is against the law," said Mr Turner"
Is it just me, or is the law actually incredibly clear? It's not illegal to take a selfie, but if that selfie has information in it that shows how someone has voted, then it is illegal to show it to anyone.
