New Delhi, Aug 16 (IANS): The Samajwadi Party (SP) Monday demanded dismissal of Uttar Pradesh Chief Minister Mayawati over the police firing on farmers in Aligarh district leading to the killing of two people.

Party chief Mulayam Singh Yadav alleged that Mayawati had a share in the contracts given for constructing an Expressway on the land the state government was acquiring and which the farmers were protesting against.

"The chief minister has a share in the contracts. It is in unwritten form. There is only one solution. The prime minister should convene a meeting of the cabinet dismiss the (Mayawati) government," Yadav told reporters in the parliament complex.

He said that his party, which is the main opposition in Uttar Pradesh, will "fight against the atrocities" on farmers in the state and in parliament.

Both the houses were Monday adjourned after disruptions over the killings during demonstrations Saturday night against inadequate compensation for acquisition of land in an area bordering Aligarh and Mathura districts.

The SP leader opposed both the Noida-Agra Yamuna Expressway and the Greater Noida-Ballia Ganga Expressway projects of the state government.

"The Ganga river is being squeezed," he said.

"The central government should intervene and scrap these projects", Yadav said, adding that existing roads were sufficient and there was no need of expressways.
