Jharkhand Chief Minister Raghubar Das hit out at the Congress on Monday, demanding an apology from the party for allegedly compromising national security in the AgustaWestland chopper deal.

"Sonia Gandhi (UPA chairperson) and the Congress party should apologise to the country for compromising with national security," the chief minister said.

As part of its nation-wide campaign to attack the Congress over the statement of Christian Michel -- the alleged middleman in the deal -- to the Enforcement Directorate (ED), the BJP fielded its chief ministers and top leaders in state capitals across the country.

The BJP stepped up its attack on the Congress and its leaders in the wake of the alleged reference made by Michel about one "Mrs Gandhi", as told by the ED to a Delhi court.

"The ED investigation has made it clear how the irregularities were committed in the deal," Das said.

The Congress, has, however, rejected the allegations and has counter-alleged that it was the Modi government that was a "protector, benefactor and promoter" of AgustaWestland.

The party has also expelled Aljo K Joseph, an office bearer in its youth wing, after he appeared as a counsel for Michel.
