The matter was raised in Friday’s drivers’ briefing when Kevin Magnussen asked why he got a penalty for his move on Nico Hulkenberg in Hungary but Alonso escaped sanction in Belgium.

It came after Palmer said he believed Alonso’s driving was “identical” to Magnussen’s move, which pushed Hulkenberg wide and promoted the “suck my balls” post-race row.

Alonso and Palmer went side-by-side into Rivage for 12th midway through the Belgian Grand Prix, with the McLaren taking the inside line and nosing just ahead at the apex.

Palmer stayed on the outside line but quickly ran out of track as Alonso held him wide, which allowed the Spaniard to pass.

Whiting showed the drivers onboard footage of both incidents, which showed that Hulkenberg had his car in front, hence Magnussen was given a penalty.

While it was very marginal, close inspection of the footage showed that Palmer did not have a wheel in front and therefore the incident was not looked at by the stewards.

According to the FIA’s guidelines, which were made clear to the drivers back in 2013, if a driver is intending to overtake on the outside, and at the apex of the corner he is in front, he must be given room on the exit of the corner.

As Alonso was in front, and knowing the rules, he exploited his right to use the whole width of the track and take the position.

Speaking about the drivers’ briefing, Grosjean said: “We watched a few incidents - like the Hulkenberg/Magnussen one and the Alonso/Palmer one as we didn’t know what was the difference.”

When asked what Whiting’s reasoning was for not looking at the Palmer-Alonso incident, Grosjean said: “They thought Palmer wasn’t ahead at the apex of the corner, so he didn’t have to be given the room on exit, which we’re now all aware we can now play with that room.”
