Dubbing Congress party as a "sinkingship", SAD President and Punjab Deputy Chief Minister Sukhbir Singh Badal today said more Congress MLAs would join SAD after April 2. He stated this to reporters here after addressing an election rally in favour of SAD Secretary General and Sangrur Lok Sabha candidate Sukhdev Singh Dhindsa. Badal said SAD election manifesto will be released next month and emphasis will be on boosting industry, farming and welfare measures for poor people. He described Surjit Singh Barnala as a "Congress agent" and accused him of allowing police to enter Golden Temple complex in 1985 when he was the Chief Minister of Punjab. Sukhbir blamed the UPA government for rising inflation, corruption scams and growing unemployment during its tenure of last 10 years.
