AMERICAN writer and political activist Naomi Wolf has received "hundreds" of reports of Scottish referendum ballot papers being issued without identifying numbers.

The author of bestseller The Beauty Myth is now compiling a list of testimonies from those who believe the back of their ballot paper was missing an official identifying number.

A internet petition has also been set up which states "We Demand A Full Scale Investigation Into The Blank Backed Ballots Given To Many Voters In The Scottish Referendum On 18th September 2014."

Last night a spokesman for the Electoral Commission said they had received complaints about the 'blank' ballot papers but could not confirm how many.

The result of the referendum can be challenged by a judicial review, providing it is brought within six weeks of the announcement of the result of the vote.
