Mohammed Ben Sulayem, president of International Automobile Federation (FIA), has told F1 team bosses he will step back from the day-to-day running of the sport and leave it in the hands of professional managers instead.

The announcement on Wednesday came after recent controversies triggered by the 61-year-old Emirati, who has been in office at the Paris-based governing body since the end of 2021.

The BBC and Sky Sports television quoted Ben Sulayem detailing the changes in a letter, seen by them, to the 10 teams.

"My stated objective was to be a non-executive president via the recruitment of a team of professional managers, which has now been largely completed," he said.

"Therefore, going forward, your day-to-day contact for all matters on F1 will be with (head of single seater racing) Nikolas (Tombazis) and his team, while I will focus on strategic matters with my leadership team."

The FIA announced changes to its F1 structure last month with Steve Nielsen, who has decades of experience with various teams, joining from the commercial rights holder as sporting director.

Tim Goss, a former McLaren technical director, moved up from deputy technical director at the FIA to become Tombazis's replacement.

Francois Sicard, previously sporting director, was handed a new role as head of F1 strategy and operations, responsible for long-term strategic planning and key trackside activities and logistics.

The FIA has also appointed Natalie Robyn, an American, as chief executive.

Relations between F1 and the FIA have frayed during Ben Sulayem's presidency on issues ranging from sprint races to restrictions on drivers' making political statements and his support for an 11th team.

F1's top lawyer sent an extraordinary letter to the FIA last month accusing Ben Sulayem of interfering in the commercial rights "in an unacceptable manner" after he questioned a valuation.

This year's season starts in Bahrain on March 5.
