Advantages of referendums
Demonstrate the pure and popular will of the people.
Referendums can mend societal rifts, such as in Northern Ireland.
Referendums can resolve political questions, such as the UK's status within the EU.
Can serve as a 'litmus test' to gain the expressed consent of the people such as the devolution referendums in 1997.
Arguably voters are much more well-informed now due to social media and political education.
Disadvantages of referendums
Voters lack the political knowledge to understand complex issues like leaving the EU.
Referendums can ignite social rifts; such as in Scotland after the failure of the 2014 IndyRef and the 2016 Brexit Referendum.
Excessive use of referendums can undermine representative democracy.
Referendums represent 'tyranny of the majority' ; in 2016, Scottish voters argued they were being taken out of EU against their will by the English majority.
Voters can be manipulated by the media and politicians by emotions.
Referendums reduce complex issues to binary questions.
Advantages of representative democracy over referendums
Representatives more likely to adopt a rational approach to questions; many voters worried about immigrants harming 'British values' whereas MPs could weigh up the benefits of immigration.
Elected politicians have an army of expertise; MPs have advisers, think-tanks, pressure groups, and select committees to gain information whereas voters rely on the media which can be biased.
Elected representatives have to balance the interests of minority and majority; Ken Livingstone introduced congestion charge in 2003 taking into account many.
