The first series, which started in late August and now has two episodes left to air, has averaged 7.7 million viewers so far, making it ITV’s highest rating drama this year.
In it, Jenna Coleman stars as the young queen and Tom Hughes as her cousin, and future husband, Albert.
Both have confirmed that they will reprise their roles in the next series. It is not yet known which cast members from series one will join them.
Daisy Goodwin, who wrote and executive produced the show, said: “Even though she reigned in the 19th Century, Victoria is a heroine for our times.”
