Is the deputy prime minister second in command of the government or is the treasurer second in command?
Deputy prime minister is just the prime ministers lapdog.They have no real power, has no real cabinet post.The finance minster is the second most important position in government because they are the one in charge of the countries finances.If the prime minister where to die or get too ill to his job.The deputy prime minister does not automatically take his place.It`s up to the party to pick a new leader.It could end up being the deputy prime minister,but that`s up to the party..Also many prime ministers don`t even have a deputy prime minister since the job is really nothing but a honourable position and has no importance in government. Parliament is the one in command,the prime minister is just the leader in parliament and must at all times have the confidence of parliament to lead.If he loses the confidence of his party the party can replace him at any time.If the government loses the confidence of parliament the government falls and theirs an election.
