The final YouGov poll has suggested a 28 seat Tory majority, although a hung parliament is still a distinct possibility – but what does a hung parliament mean?

The final YouGov MRP poll has predicted the Conservatives will win 339 seats with 43 per cent of the vote share.

It predicts Labour will take 231 seats, the SNP 41, the Liberal Democrats 15, Plaid Cymru 4, the Green Party 1 and the Brexit Party 0.

YouGov interviewed about 100,000 voters and has process that data through a statistical model to predict constituency results nation-wide.

However, YouGov has admitted the surprise element of tactical voting and the tightening in the polls meant a hung parliament could not be ruled out.

A hung parliament occurs when no political party has enough seats in the House of Commons to secure an overall majority.

With 650 seats in the commons, a party needs to win at least 326 seats to have a majority.

Governing without a majority makes it harder to pass bills and legislation through parliament.

If a hung parliament is declared following December 12, Boris Johnson will continue as Prime Minister.

Johnson will then be faced with the decision whether to create a collation with another party or to govern with a minority.

In 2017 Theresa May’s Conservative Party lost their majority, winning just 318 seats.

The resulting hung parliament led May to forge a "confidence and supply agreement" – not an official coalition – with Northern Ireland’s DUP.

The DUP agreed to support the Tories on certain matters in return for extra funding for Northern Ireland.

Chris Curtis, YouGov's political research manager, said: "The margins are extremely tight and small swings in a small number of seats, perhaps from tactical voting and a continuation of Labour's recent upward trend, means we can't currently rule out a hung parliament.

"As things currently stand, there are 85 seats with a margin of error of 5 per cent or less."
