The party accused the Congress-led state government of favouritism in the allotment of these tenders.
"Tenders of Rs 4000 crore were alloted to contractors in a hush-hush manner, and donations for the party fund were collected on the eve of the Assembly polls," BJP co-incharge of party affairs Kirit Somaiya said here.
The BJP leader demanded a fair probe into the case by a competant authority before the Assembly polls.
