The Congress, Telugu Desam, TRS and BJP have promised to mobilise crowds from districts to make the ‘Million March' to Hyderabad' on Thursday a success.
The CPI had also expressed its support to the programme earlier.
The Telangana Joint Action Committee chairman M. Kodandaram maintained that thousands of people were arrested in districts to prevent them from reaching the city but a senior police officer said the number did not exceed a few hundreds.
A ‘meet the press' programme organised by Telangana Journalists Forum on Wednesday turned out to be a platform for the parties to announce support to the programme.
Congress MLA (Station Ghanpur) T. Rajaiah said people were in no mood to stop if they were prevented from reaching the city from districts.
Telugu Desam Party legislator G. Jaipal Yadav said he found police check posts to stop people in all the mandals of his native Kalwakurthy constituency in Mahbubnagar district.
The TDP urged its entire cadre to participate in the programme.
All the district presidents and in-charges of 119 constituencies in Telangana were asked to mobilise crowds.
If required, the TDP MLAs would return to their constituencies and bring the crowds.
The TRS floor leader in Assembly Eatala Rajender said at least ten check posts had come up along the 170 km highway from Hyderabad to Karimnagar. At Uppal railway station in Karimnagar, train commuters were arrested.
He said the MLAs will go in a procession from Assembly to Tank Bund.
Former Union Minister of BJP Ch. Vidyasagar Rao questioned the prohibitory orders clamped by police in the city as they applied to unlawful gatherings. Balladeer Gadar criticised the government for setting up obstacles to what was supposed to be a peaceful march.
