Colombians plan unusual election protest

Sunday is election day in Colombia and a lot of people who are fed up with their politicians are planning an unusual protest.

About 33 million people are expected to vote for a new Congress, but the country is known for its low voter turnout.

And now a new movement that asks voters to mark their ballot paper as "none of the above" is gaining momentum.
