Changed The Way You Kiss Me - which includes namechecks for chart veterans Al Green and Jack Jones (the latter only as a cockney rhyming slang term) - is his seventh chart entry since his debut 20 months ago, his fifth as primary artist and his first number one.
It sold 115,046 copies last week - the highest tally for a number one for 10 weeks -and is the first single from Example's third album, Playing In The Shadows, which is scheduled for release this Autumn.
After three weeks at the summit, Give Me Everything slips to number two for Pitbull, Ne-Yo, Afrojack & Nayer, selling a further 66,898 copies.
Nicole Scherzinger's latest single, Right There, improved only 15-14 last week but leaps to number three (51,355 sales) following her performances of it on the final of Britain's Got Talent and The Graham Norton Show.
Including her Pussycat Dolls releases, it is Scherzinger's 17th hit. It is the fourth from her debut solo album Killer Love to make the Top 10, following the number three hit Poison, Heartbeat - a number eight collaboration with Enrique Iglesias - and Don't Hold Your Breath, which reached number one in March.
The album climbs for the third week in a row, springing 35-22 (7,250 sales). There are also Britain's Got Talent boosts for Tracy Chapman's Fast Car, which accelerates 28-13 (20,720 sales) after being performed for a second time by Michael Collings and Josh Groban's 2001 recording To Where You Are, which makes its Top 75 debut at number 53 (4,790 sales), after proving a winning choice for Jai McDowall.
It's three years next week since Coldplay scored their one and only number one single with Viva La Vida and they return to the Top 10 for the first time since with new single Every Teardrop Is A Waterfall, which debuts at number six (37,187 sales). The first single from the band's upcoming fifth album, it is their 14th Top 40 single to date.
It's been a good year for continental acts on the singles chart so far. The current chart includes entries from several, including Italian dance doyens Alex Gaudino and Benny Benassi, who are joined, somewhat unexpectedly, by their compatriot, classical pianist Ludovico Einaudi, whose 2001 instrumental I Giorni debuts this week.
Previously used by the BBC in trailers for its Royal Wedding coverage, the track owes its break to Radio One's Greg James, who fell in love with and downloaded it when he was studying for his University examinations a few years ago.
James played it as a 'study break' record on the Zane Lowe Versus Greg James show on Radio One last week and was immediately inundated with requests for information. He has played it several times since, and the track sold 11,004 copies last week to debut at number 32.
Falling 19-39, the title track of Lady GaGa's album Born This Way nevertheless becomes her sixth single to sell more than half a million copies. Overall sales of 505,924 include 9,301 last week.
Singles sales are down 0.75% week-on-week at 3,167,407 - 13.50% above same week 2010 sales of 2,790,756.
