Accusing the UPA government of burdening the common man by increasing fuel prices, the Left parties on Wednesday announced a week-long agitation across the country against the hike.

Senior Left party leaders termed the fuel price hike as a "slap on the face" of the common man and said it revealed the "anti-people" policies of the Congress-led coalition.

The supporters of the four Left parties - CPI(M), CPI, RSP and Forward Bloc - will hit the streets from Thursday morning to force the government to roll-back the hike, senior Left leaders Abani Roy (RSP) and G Devarajan (Forward Bloc) said.

"The decision to hike the prices of fuel revealed the actual face of the UPA. They are putting all the burden on common man," said Devarajan.

He said that the decision will have a "huge impact" on the household budget of the common man.

"The government has increased the prices of petrol, diesel and domestic cylinders. There is no mention on winds fall profits. The government has not touched the corporates who export fuel and make huge profit. The UPA is taking away all money from the pocket of common man," he said.

Roy accused the government of passing on the burden to common people. "The government has no concern about the common man. We will do whatever we can do to force the government to review it," he said.

Asked whether the hike would lead to a discussion among Left parties on withdrawing support to the government, he said, "The Left parties will discuss about withdrawing support in a meeting scheduled later this month. RSP alone can't take a decision," Roy said.
