The CPI(M), CPI, RSP and Forward Bloc will come out with a ‘chargesheet’ citing UPA's several drawbacks and failures, including "rising prices and inflation, surrendering of national interest, and unkept promises with regard to the Common Minimum Programme (CMP)", a senior Left leader said.

Feeling ‘hurt’ by Samajwadi Party's ‘betrayal’, the Left parties will also "expose the marriage of convenience" between Congress and SP in its campaign, said the leader on condition of anonymity.

The Left campaign against the UPA will be launched on July 14 in the capital, where top Left leaders will ‘attack’ the Government for its ‘refusal’ to take appropriate steps to tackle the runaway inflation and back-breaking price rise besides explaining their opposition to the deal.

Plans are afoot to field top leaders itself, who will criss-cross the country attending public meetings and rallies organised in major towns in all states, to explain the Left position.
