The minister sought to speak something in the House, when Soren said the Opposition would not hear from an "accused minister," triggering a strong resentment from Singh, who repeated charges of land grabbing against Soren.
Stating that he has the right to speak in House, Singh claimed he had evidence against Soren allegedly grabbing tribal land at various places in the state.
Singh denied both the allegations on Monday last. Later, Singh told reporters he would produce evidence in support of his allegations against Soren at a press conference in a couple of days.
The minister alleged that Soren's accusation against him was a revenge for the nod he gave to the CBI to prosecute the JMM leader's sister-in-law Sita Soren in connection with a corruption case.
