Alexander Albon has been demoted to the back of the grid for both races two and three at Portimao after being unable to provide the mandatory 1kg of fuel after the session.
The Signature driver and Lotus F1 Junior had originally qualified on pole position for race two, but will now drop to the back of the field as punishment, while he will also lose his twelfth place start for race three.
Albon had been the only driver to get ahead of the Prema Powerteam drivers for race two, with the Italian team now locking out the front two rows of the grid with championship contender Felix Rosenqvist now assuming pole position ahead of series returnee Nick Cassidy, while Ferrari Driver Academy driver Lance Stroll and Racing Steps Foundation-backed Jake Dennis now line-up on row two.
Prema will also start race one from the front with Dennis taking pole, while Rosenqvist will also start race three from the front.
