Kenyan sports betting operator SportPesa will cancel its sponsorship of local sports bodies after the country approved significant tax hikes on gambling revenue.

On Friday, SportPesa CEO Ronald Karauri used his personal Twitter account to announce that his company would be “giving notice to clubs and unions that from January 1 we will withdraw all sponsorships.” Karauri said he was announcing the move in advance to allow “our sports partners to plan accordingly.”

The January 1 timeline dovetails with the start date of Kenya’s new gambling tax regime. Kenya’s President Uhuru Kenyatta signed the Finance Bill 2017 into law earlier this week, imposing a uniform 35% tax on all gambling revenue.

Betting operators like SportPesa had previously paid only 7.5% tax on revenue derived from Kenyan punters. Kaurauri said the new tax meant that it would be “impossible to continue funding the [sports] sector.”
