Renault's Daniel Ricciardo has been disqualified from Singapore GP qualifying for a technical infringement.
Ricciardo had qualified eighth but will now start from the back of the field in Sunday's race, which begins at 1.10pm.
Team-mate Nico Hulkenberg takes over eighth and McLaren's Lando Norris moves into ninth, while Alfa Romeo's Antonio Giovinazzi gains the final top-10 starting slot.
Ricciardo's Renault car was found to have contravened the regulation governing how much power can be emitted by the MGU-K element of the engine. The RS19 was found to have exceeded 120kW during Q1.
The issue was referred to the stewards by FIA technical delegate Jo Bauer after qualifying and, after speaking to Renault representatives into the early hours of Sunday morning at F1's night race, stewards announced just before 3am local time that they had determined a breach had taken place "beyond any doubt".
