Citizenship laws 'bloody shambles': Greens

Greens senator Nick McKim has lashed out at the federal government's proposed citizenship laws, slamming them as a "bloody shambles".

Senator McKim accused the government and opposition of "outrageous collusion", after the legislation to strip citizenship from dual national terror suspects was rushed into the Senate on Monday night, before the Greens were given time to look at it.

"This is a disgraceful abuse of parliamentary process - they are treating this parliament with utter contempt," he told the Senate.
