The Spaniard accused the race stewards of enjoying the beer supplied by F1’s sponsors after an incident in which Briton Jolyon Palmer passed him, by cutting out the second chicane.
Alonso believed the stewards misjudge the incident and did not react properly, launching into an outburst of radio messages to his McLaren-Honda team.
The incident had enabled Palmer of Renault to take 12th position in the race – which he refused to give back, as is conventional when a driver cuts out a chicane.
The stewards eventually caught up with events and gave Palmer a five-second penalty before he retired with mechanical problems.
He was later told of Palmer’s misfortune at having to bring his car into the pits to retire, something Alonso declared was “karma” — only to be called in by McLaren to do the same with three laps to go.
“When we arrived at the chicane we were side-by-side… We braked late and I managed to take the chicane, but he didn’t and he jumped it and stayed in front. Alonso Speaking after the race
“Usually, that’s something that’s very clear in the rules – when two cars are side-by-side at the chicane and one gets to take it and one doesn’t, you give back the position – but this time the FIA must have been having a Heineken.
“It was not up to F1 standards. There is not an interpretation possible there. It is black and white, but anyway, fighting for 16th and 17th, it doesn’t matter.”
The double world champion was also forced into retirement on the penultimate lap with gearbox problems.
Palmer said he blamed Alonso for their incident at the chicane.
“I was ahead coming in, he braked super-late and forced me off the track – I’m sure it will be another talking point at the next race because Fernando is not very happy about it, but I don’t care.”
The pair also clashed at last weekend’s Belgian Grand Prix, triggering the bad blood that was prevalent in Sunday’s race.
