Simon Bridges has taken the Immigration Minister to task over the Sroubek case.

It's been revealed Iain Lees-Galloway didn't read the full file on Karel Sroubek, when deciding whether or not to let the convicted drug smuggler stay in the country.

The National Party leader told Larry William Lees-Galloway has to go.

"If there was ever a case that went before a Minister that had flashing red lights on that said 'read me and deport', this was it."

Bridges says the writing is on the wall for him. 

"Now we're really only arguing I think about the time when he is gone."
