The man who took a private prosecution against John Banks says he will do the same against Labour leader David Cunliffe if police do not charge him over a tweet he posted.
The Electoral Commission yesterday referred Mr Cunliffe to the police in relation to the post on social media site Twitter, in which he encouraged people to vote for Labour's candidate in the Christchurch East by-election on the day of the poll.
The tweet said: "If you are resident in Christchurch East don't forget to vote today - for Labour and Poto Williams."
The commission said it referred the matter to police, as it is in breach of rules banning politicians from influencing voters on Election Day.
Today former accountant Graham McCready said he was prepared to take a private prosecution against the Labour leader.
