Cancelled votes on the rise
The number of cancelled votes rose despite various awareness campaigns, the Election Commission said.
EC officials said even though the voter turnout was much higher than the national election, there were more cancelled votes simply because of a lack of awareness.
There are too many symbols on the ballot paper and often voters do not fold them properly, they said.
In the first phase, 461,383 votes were cancelled. In the second phase, 562,955 votes were cancelled.
As many as 369,855 votes were cancelled in the third phase.
