National's Nick Smith has again got offside with Parliament's Speaker Trevor Mallard and has been booted out of Parliament for the day.

Smith crossed swords over who gets to write the question on referenda.

Mallard believes he was being deliberately provocative.

"A member who acts deliberately indicates to me that it is his wish to be named. I am not going to grant him his wish, but he is going to leave the Chamber and he will not return today." 

Smith was recently named by the Speaker, meaning he lost a day's pay after being thrown out.
