(CNN) Pop star turned MP Bobi Wine is making plans for a bigger political stage in the country and says he has launched a grassroots movement for young people aimed at challenging the country's longtime leader President Yoweri Museveni.

Speaking with CNN's Robyn Curnow Wine said he is "seriously considering" running for president in 2021 where he is expected to face Museveni who has ruled Uganda since 1986. Museveni has changed the constitution twice to extend his stay in office, although he has not declared his intention to contest in the next elections.

Wine said dictatorships have thrived in Africa by suppressing young people, and getting young voters to the polls could help change the game.

"Ugandans cannot be free unless they free themselves from military rule and lawless rule," Wine said.

"We started a campaign calling upon all people of Uganda, especially the young people that have been so apathetic to go ahead and register themselves and be voters. Not just supporters but voters."
