After suffering a number of disappointment’s on the world stage the question remained as to whether the Liverpudlian would ever be able to put a complete series of events together and finish on top of the podium.
With a season’s best time of 8:36 set in the 60m hurdles and the high jump standings topped with a clearance of 1.91m, the former Liverpool Harrier then set an indoor personal best in the shot put with a throw of 12.68m.
She claimed the lead in the competition after the fourth event with an impressive leap of 6.50m in the long jump meaning she had to finish within 2 seconds of nearest rival Ivona Davic to confirm gold.
Instead of being cautious, the 25-year-old finished the event off in style storming home to win the 800m, finishing with 4,750 points, banishing the mental demons which had plagued her in the 2016 Olympics as well as the 2015 and 2017 World Championships.
It ended Johnson-Thompson’s long wait for a major title after not tasting success since the 2015 European Indoor World Championships.
The heptathlete moved to France at the end of 2016 and it is a decision which she believes has benefited her in the long run after initial growing pains.
She told BBC Sport: “I can’t believe it. I’ve dreamed of this for so long.
“I had to leave my two dogs with my mum. It’s lonely out there in France, the language barrier is difficult but it’s worth it for a night like this.”
Social media was full of messages for the athlete with former Olympic Champion Dame Jessica Ennis-Hill leading the congratulations on Twitter.
Congratulations @JohnsonThompson World Champ!! You must be so happy and exhausted. Pentathlons are long hard days. Enjoy celebrating now x

Her attention now turns to the Commonwealth Games being held in Australia next month where Johnson-Thompson will hope to build on this success and clinch another gold medal.
