Protesting adivasis will hit the streets of Assam on Friday to highlight their grievances before United Progressive Alliance chairperson and Congress president Sonia Gandhi [Images] during her day-long visit to Guwahati.

Sonia will be addressing a farmers' rally to be organised by the ruling Congress party, besides attending an award presentation ceremony organised by Assam government in the afternoon.

The adivasis are planning a massive protest even as the ruling Congress is making an all out effort to make Sonia's rally a grand success to silence opposition political parties, which have launched a state-wide campaign against the 'misrule' of the Tarun Gogoi-led Congress government in the wake of arrest of the former state education minister Ripun Bora, by the CBI in New Delhi on June 3 on a bribery charge.

He was arrested while trying to bribe a deputy superintendent of the central investigating agency probing the September 2000 murder of tea tribe student leader Daniel Topno, a political rival of Bora.

The ruling party has asked all the 54 party MLAs to bring farmers and other people in large numbers from their respective constituencies to the 'kisan rally' to showcase the party support base before Sonia, even after the embarrassing Ripun Bora episode.

Ripun Bora has already been suspended from the party in a damage control exercise carried out with approval from the All India Congress Committee and to gag the opposition diatribe.

The All Adivasi Students' Association of Assam is out to derail Congress' plan for a massive farmers' rally.

The AASAA has declared a series of month-long agitation programmes that will be launched the day Sonia arrives in Assam to register their protest against 'misrule' of Congress and demanding exemplary punishment to former education minister Ripun Bora for masterminding the murder of tea tribe student leader Daniel Topno way back in September 2000.
