With just days to go before the General Election - polls suggest a wide range of results could still happen.
A number of the opinion polls have been consistently pointing towards a majority for Boris Johnson and the Conservatives.
Mr Johnson called the election with the hope of achieving such a majority after the previous hung parliament repeatedly frustrated him and stopped him getting his Brexit deal through the house.
However, in recent weeks and days several opinion polls have suggested that another hung parliament could be on the cards after this election - like we saw in 2017.
So what is a hung parliament?
A hung parliament is when no party has an overall majority of MPs in the House of Commons.
It is also known as a situation of no overall control.
There are 650 seats in the House of Commons - which means that a party needs to win at least 326 of them to get a majority and form a government.
If this doesn't happen - and we once again have a hung parliament - then parties will look to form alliances, coalitions or have agreements that can take parliament forward.
What happens in a hung parliament?
When there is no majority, the Prime Minister in power before the general election stays in power and is given the first chance to create a government. They may decide:
Will the party with the most seats form a Government?
This is usually the case.
In 2017 Theresa May's Conservatives did not have a majority but as the biggest party they had the first chance to form a new arrangement and did so with what is known as a confidence and supply arrangement with Northern Ireland's Democratic Unionist Party.
This gave her the working majority she needed to form a government - if a rather flimsy one.
What about this time?
If we head into a hung parliament when the results come in on Friday - it is likely to have a different result.
The Conservatives will almost certainly be the largest party again, but it is hard to think of any other party willing to work with Mr Johnson.
The DUP are furious that the Prime Minister's Brexit deal betrays their beliefs by putting a border down the Irish sea - especially after he promised them he would never do that.
So it is unlikely that they would back up the Prime Minister.
It may then fall to Labour to try and form an arrangement with parties like the Scottish National Party and the Liberal Democrats.
