Love Island: Bookies have had their say on who could win - here's how Portsmouth girl Demi Jones might fare in Sunday's final

They were delighted as sparks flew with original islander Nas Majeed when Demi was parachuted in as a late entry, but he later dumped her.

A flirty foray with Southampton boy George Day followed but it wasn’t to be, and Demi kept her place on the show after he was sent home.

But the 23-year-old former Springfield School girl now finds herself in the series' big Sunday finale – and the bookies have had their say.

Luke Trotman and Siannise Fudge are top favourites to win the reality show's £50,000 prize at 3/10 and they are odds-on to share it.

One person per couple is given the life-changing cash sum and is asked whether they want to keep it, or split it with their love interest of six weeks or fewer.

Bookies pitch the chance of a steal, which has never happened on Love Island, at 8/1 – with sharing almost certain at odds of 1/20.

Second favourite to clinch the prize are Finley and Paige, whose Love Island relationship has lasted almost the length of the show.

They had been favourites during the majority of the series but are now faced with victory odds of 11/4.

Meanwhile Demi and her Teesider beau, Luke Mabbot, are third favourites to win with odds of 17/2.

The pair’s popularity has been slowly rising since they recently coupled up.

Bookmakers say fourth finalist couple, Ched Uzor and Jess Gale, are 35/1 to win.

Whoever wins will have to quell their amazement to be interviewed by Love Island host Laura Whitmore after the show.

The Love Island finale will last a 90 minutes and air at 9pm on Sunday, on ITV 2.
