Samoa's deputy prime minister, Fonotoe Nuafesili Pierre Lauofo, and the associate minister for trade and commerce, Muagututagata Peter Ah Him, are to be charged with criminal offences.
The acting police commissioner, Leiataua Aviga Salale, says the deputy prime minister will be charged with obstructing police which carries a maximum penalty of up to a year's jail and a fine of nearly 100 US dollars.
The associate minister, Muagututagata Peter Ah Him, will be facing a charge of failing to comply with breath testing laws.
That offence carries a maximum penalty of six months jail or a fine not exceeding 450 US dollars.
The charges come after Fonotoe allegedly instructed Muagututagata to drive away as police were trying to conduct the breath test.
