Impey won the season-opening Tour Down Under in Australia in January, and then followed it up with third place at the Cadel Evans Great Ocean Road Race on January 28 to position himself at the top of the WorldTour table – and he's been there ever since.
However, with racing now fully under way in Europe, Impey's time at the top of the ranking may well be about to come to an end.
Marc Soler (Movistar) leaped up the ranking to second place behind Impey on Sunday after winning Paris-Nice with a strong final stage performance. The Spaniard shunted team-mate Alejandro Valverde down to third spot, with Gorka Izagirre (Bahrain-Merida) moving up to fourth after third overall in Paris-Nice.
British Paris-Nice runner-up Simon Yates (Mitchelton-Scott) is in fifth.
With Impey and Yates in the top five individual ranking, it's no surprise to see Mitchelton-Scott occupy the top slot in the WorldTour team ranking. Quick-Step Floors are second behind the Australia team, with Bora-Hansgrohe in third.
Things may change on Tuesday, when the Tirreno-Adriatico stage race concludes in Italy and results are added to the ranking. Impey is one of those taking part.
The next WorldTour events after that are Milan-San Remo (March 17), Volta Ciclista a Catalunya (March 19-25) and E3 Harelbeke (March 23).

Boels-Dolmans dominate women's WorldTour so far
The second race in the 2018 women's WorldTour took place on Sunday – the Ronde van Drenthe. Dutchwoman Amy Pieters (Boels-Dolmans) took the honours in the Netherlands race to position herself in second spot in the women's WorldTour ranking behind team-mate Anna van der Breggen.
Van der Breggen tops the women's ranking after taking victory in the first race in the women's WorldTour calendar: Strade Bianche.
Needless to say, Boels-Dolmans therefore sit at the top of the team ranking, comfortably ahead of Ale-Cipollini and Canyon-SRAM.
The Trofeo Alfredo Binda in Italy is the next race in the women's WorldTour calendar, followed by Driedaagse De Panne-Koksijde in Belgium on March 22.
