If you are an MP in the Greek Parliament, would you be able to be sworn in, in French? Of course not.
NZ has three official language – English, Maori and Sign Language. I don’t know why he thought any other language would be permissable.
Also on the ZB report:
He says he is going to Parliament not just as an MP for Mangere, but for all Samoans and it is the second most spoken language in his electorate.
When did all the Samoans in NZ get together and appoint Sua as their MP? Is he claiming to represent all the other Pacific Island MPs also?
