James Newman has produced the UK's best Eurovision entry in years - but will that be enough?

The 31-year-old, whose younger brother is Brit Award nominee John Newman, has already written for Ed Sheeran, Jess Glynne, Calvin Harris and Little Mix.

He got a Brit Award and a Grammy nomination for his work on Rudimental's song Waiting All Night. On the other hand, he co-wrote Ireland's 2017 Eurovision entry, Dying To Try, and got knocked out in the semi-finals.

In May, he'll head to Rotterdam as a solo artist with a mid-tempo banger called My Last Breath. It's short and direct, with the sort of "woah-oh" hook that would make Chris Martin envious.

"That was definitely intentional," says the singer, who wrote the song in January. "We wanted to create an anthemic post-chorus that makes everyone feel involved."

"Can you imagine 20,000 people in the arena going 'woah-oh-ohhh'? It's something you can sing along to without knowing the lyrics."

Newman's selection comes after a dismal run for the UK at Eurovision. Last year, Michael Rice's Bigger Than Us came last, scoring just 11 points.

As a result, the BBC scrapped the public's role in the selection process and invited music company BMG to help it find this year's entrant.

"We started with the sole aim of changing the perception of the contest," said Alistair Norbury, the company's president of repertoire for the UK.

That's all well and good - but the perennial argument is that Eurovision's voting system is broken, with the UK being "punished" for everything from the Iraq war to Brexit.

Yet over the years, several academic studies have looked into political voting, and found little evidence that it affects anything beyond the mid-table results.

Countries do vote for their neighbours and allies - but the winner needs pan-continental support to rise above the pack. Songs that come last tend to be boring, unconvincing or poorly-performed.

So how does My Last Breath compare with the competition?

Here's a quick guide to some of the contenders - with the caveat that some of Eurovision's big hitters, including Sweden and Russia, are yet to reveal their entries.

Lithuania: The Roop - On Fire

An early favourite with fans, On Fire is essentially a trance remix of Billie Eilish's Bad Guy, performed by Right Said Fred.

It's better than that makes it sound, though, with a catchy chorus and squiggly synth line that quickly lodge in your head.

The choreography is weirdly compelling, too: Singer Vaidotas Valiukevičius looks like he's been allowed to watch all the Fortnite dances once, then tried to recreate them from memory. Voters will lap it up.

Can James Newman beat them? He has the better song, but The Roop are classic Eurovision crowd-pleasers.

Albania: Arilena Ara - Shaj

Eurovision wouldn't be Eurovision without a windswept ballad or 12, preferably sung at top volume by a woman with too much hair.

On that front, Arilena Ara more than delivers. Her song is literally called "scream" and she belts out the high notes with all the subtlety of a klaxon in an elevator shaft.

But the song's cleverly constructed around those big moments, breaking down to a quiet string section in the mid-section before ramping to the final chorus.

Arilena has the experience to pull it off, too. Since winning The X Factor Albania in 2013, she's become one of the country's biggest stars, with more than 1.1 million followers on Instagram. Her single Nentori has also been a hit in Russia and Romania, which means she'll be familiar to voters there.

Can James Newman beat her? No. Shaj is an early favourite amongst Eurovision-watchers, and looks set for a top five finish.

Latvia: Samanta Tina - Still Breathing

Samanta Tina has been chosen as Latvia's Eurovision contestant on her fifth attempt; and heads to Rotterdam with a strident hymn to female empowerment.

It starts well. Tina's vocals sizzle with attitude and she seems to be building to a killer chorus. But then she deploys the "pop drop" - swapping out the melody for a distorted, heavily-filtered synth.

It's a technique that arrived, peaked and outstayed its welcome in the space of about six months in 2015; and completely kills the momentum of this Gaga-indebted bop.

Her rap in the middle-eight doesn't improve matters; and the whole enterprise eventually collapses like a soufflé that's been poked by Paul Hollywood.

Can James Newman beat her? If there's any justice, yes.

Australia: Montaigne - Don't Break Me

Australia take Eurovision very seriously - ending up in the Top 10 four times in the last five years - and this year is no exception.

Their entrant is Aria Award-winner Montaigne whose song, Don't Break Me, is a dramatically-spun story of tortured love. Driven by pounding drums and soaring chorus ("You thought I was elastic / But maybe I'm just made of glass") the track sounds distinctly like the work of another Australian pop star, Sia.

The singer's stage presence is as striking as her song. She wears Elizabethan ruffles in reference to the humanist philosopher Michel de Montaigne (after whom she's named), while her complex choreography will keep Eurovision's camera crews on their toes.

Can James Newman beat her? Unlikely.
