Liberation Tigers of Sri Lanka love to claim that they are the sole representatives of tamil people. Have they been appointed to positions by the Tamil people ? No. Do they contest any election to represent themselves?No.
One the other hand they have eliminated all the leaders of other Tamil Parties. Not only that they assasinated all the Tamil leaders who stood for a political solution based on devolution, Luxman Kadiragarmar, Neelaan Tiruchelvam and Kethish Loganathan are a few examples.
Therefore an alternative Tamil Party cannot be survived without a armed group.
