The NSW Parliament has descended into chaos this morning, with the Government pulling the plug on the Legislative Council last night to avoid having its plan to sell off NSW Lotteries put to a vote.

The Rees Government is now facing a full-blown crisis to get any legislation through the Legislative Council.

The opposition claimed this morning that such a move to "collapse" the house had not occurred since the 1920s.

The crisis has risen because the Shooters Party has been voting against the Government all week after cabinet failed to back the Shooters Party's push to hunt in national parks.

With the opposition and Greens opposing the Lotteries privatisation, the Government needed the support of the two Shooters Party MPs.
