Level playing field

We have been listening from different political parties, different political leaders even from different ambassadors regarding the “Level playing field” for the parliamentary elections since the BNP-Jamaat alliance handed over power in 2006. What I understand regarding the level playing ground is that all, parties and individuals want a fair election and as a law abiding citizen I also want the country to have a fair election.
Since it is the job of the Election Commission, I believe that they are working in the above area and probably they will be able to hold a free and fair election. What I have failed to understand is that some political parties and some of the leaders, who have not won a seat in the last couple of elections, are demanding the same from the government and the Election Commission. I think their demand is pointless.
Since the topic of level playing field has been raised and the present government and the Election Commission are working on this issue, I feel the EC should also come forward and announce that the parties which have not won a seat in the last three elections will not be eligible for registration with the EC.
They will have to restart their political carrier by taking part in the upazila level elections and step by step (if they win) they should reach the JS level.
The government and the Election Commission should take up this agenda and if necessary they can go for a referendum as elections are all about the people's choice. Bangladesh is for the entire Bangladeshis, and not for any particular political party or family.
