Spa Euro F3: Jensen and Dennis claim poles for races two and three

Jensen, the reigning ADAC Formel Masters champion, popped into the top spot just moments before the session was red-flagged for a second time, and with less than a minute remaining it was not restarted.

It was the second stoppage of the session, during which times tumbled throughout as the racing line dried out.

Jensen's achievement means he is the first non-Prema Powerteam driver to top an F3 qualifying session this season, although Felix Rosenqvist was stripped of two of his pole positions at Silverstone for a technical infringement.

Ironically, Prema reckoned that Jensen gained his time because of a slipstream from the Italian squad's Brandon Maisano, who joins the Mucke Motorsport Dallara-Mercedes on the front row for race two.

But Jensen attributed his pole to Mucke's low-rear-wing set-up.

"It was really difficult," he said. "You could watch a little bit the guys in front and see how slippery it was, but it was really bad in the last two corners [Stavelot] before the Blanchimont straight.

"I nearly went off on the first of the right-handers, but the car felt good and I did the time."

Jensen and Maisano leapt to the top just as Prema twins Lance Stroll and Rosenqvist were trying to find a clear space in traffic for a last-lap attack.

Up to this point, rookie Stroll sat on pole after enjoying a strong tow from Rosenqvist, but they ended up third and fourth in the final reckoning.

On the third row for race two will be Scot Sam MacLeod (Motopark) and Fortec Motorsport's Pietro Fittipaldi.

Dennis ended up only seventh in the overall times, but with such inconsistent track conditions the order is considerably jumbled over the two grids: the Briton's second-best time, which forms the grid for race three, was less than a tenth slower than his fastest.

Jensen and Maisano are second and third behind the Racing Steps Foundation-backed Prema driver, with Motopark runner Markus Pommer (11th overall) taking fourth for race three.

Once again MacLeod and Fittipaldi share the third row, with Rosenqvist and Stroll languishing on the fourth.

Santino Ferrucci, Dorian Boccolacci and Sergio Sette Camara round out the top 10 on the grid for race two, with Sette Camara and Callum Ilott forming the fifth row for race three.

It was a miserable session for championship leader Antonio Giovinazzi (12th and 18th) and second-in-points Charles Leclerc (a pair of 13ths).

The first red flag was caused after seven minutes by Alexander Albon crashing at Stavelot, while the second was triggered by a shunt for Ilott.

Meanwhile, a stewards' decision from first qualifying means Camara has earned a five-place grid penalty for forcing Martin Cao off the track - Cao himself earned a reprimand for blocking the Brazilian.
