Muhoozi Kainerugaba has said he will win the presidency if his father President Yoweri Museveni allows him to vie in the 2026 general election in Uganda.
In a tweet, the President's son said Ugandans will be shocked by the amount of support his family will get.
"If my father allows me to stand in 2026, We will shock the entire country by the amount of support we have," he tweeted.
Muhoozi has been making headlines of late because of his controversial statements.
In October 2022, Muhoozi caused uproar in Kenya after threatening to "capture" Nairobi.
After bitter reactions from Kenyans that almost caused diplomatic crisis between the two countries, President Museveni asked Kenyans for forgiveness.
His apology came a day after he sacked Muhoozi as commander of the army's land forces.
But Museveni softened the blow by promoting him to the rank of general, and retaining him as his adviser.
Museveni has long been suspected of grooming the 48 year old to succeed him when he eventually steps down.
Muhoozi has increasingly been entering the political arena, with his critics saying this was in breach of the military's code of discipline.
His latest intervention came when he sent out a series of tweets - some serious, some in jest - about Kenya.
Muhoozi apologises
He said he had spoken to Kenya's former President Uhuru Kenyatta, and expressed regret that he had stepped down at the end of his two terms in August.
"My only problem with my beloved big brother is that he didn't stand for a third term. We would have won easily!" Muhoozi said.
He said: "It wouldn't take us, my army and me, 2 weeks to capture [Kenya's capital] Nairobi."
This led to an uproar on Twitter, with people accusing Gen Kainerugaba of being "reckless" and jeopardising relations between the neighbouring states.
It led to him urging Kenyans to "relax".
"I would never beat up the Kenyan army because my father told me never to attempt it! So our people in Kenya should relax!" He tweeted.
