McLaren's Lewis Hamilton will again face questions over allegations that he drove too aggressively during last month's Bahrain GP.
The accusation relates to an incident in which both Hamilton and Fernando Alonso were forced wide by Mercedes driver Nico Rosberg.
While Alonso backed off, Hamilton failed to slow down and passed Rosberg by leaving the track.
Such a manoeuvre is against the rules and, although Hamilton and Rosberg were later cleared, the topic is likely be keenly discussed at this weekend's drivers' meeting.
Red Bull driver Marc Webber explained: "It was a situation that Lewis didn't want to find himself in, off the track, but he stayed with it and ultimately the move was kept.
"I'm sure we'll talk about it in the drivers' briefing."
Hamilton recorded the fourth-fastest lap in the second practice session ahead of Sunday's Spanish Grand Prix.
