This is from Republic
The job would not simply be ceremonial, our new head of state would have very clear and limited powers. Those powers would be non-political, which means that they can only be exercised according to certain official criteria.
Our elected head of state would not be allowed to make decisions based on their own political opinions (much like a judge uses their power according to the law and the facts of the case, not letting their personal politics get in the way).
What sort of powers would the head of state have?
In a republic all our politicians would have to obey a set of rules that are decided by the people (written down in a constitution and voted on by the public). The head of state would be able to stop the politicians from doing something if they are breaking the rules - but not just because they disagree with the politicians.
For example, if the constitution says that new treaties with the EU require a referendum, if the government tried to sign a new deal with the EU without first asking the voters then the president could step in. The head of state wouldn't be allowed to get involved in the debate about the merits of the EU, but would be able to insist the government followed the rules.
Also, if we have another hung parliament where no party has enough MPs to form a government, then the president would preside over the process of deciding who should become prime minister. This would ensure the process was fair and even handed and all parties had the opportunity to have their voices heard.
Our elected head of state would be free to speak out on important issues of the day, but would not be allowed to speak on party political matters or get involved in party politics. The head of state could give a voice to the people's concerns or hopes, put new issues onto the public agenda or support community groups and charities in promoting non-partisan causes.
The rules that would govern politicians would also apply to the head of state - these rules would stop them becoming party-political.
Does anything there cause concern?
