Formula 1 voted to delay the introduction of Halo and also wind back the controversial radio clampdown in a key strategy group meeting on Thursday.

While the rest of the sport set up shop at Hockenheim, team bosses, the FIA and Bernie Ecclestone were actually in Geneva in the form of the strategy group.

In Germany, the Halo debate was raging on, with British rookie Jolyon Palmer saying that most of the drivers were opposed but "don't really voice it in the press".

"He's incorrect," GPDA director Jenson Button hit back, "and it's very unfair for him to speak for other drivers. [Halo] is a great solution."

However, the strategy group voted to delay it until 2018, while F1 supremo Ecclestone suggested that Halo could be scrapped altogether.

"The Halo maybe is not the right way to go," he told The Telegraph. "We're going to come up with something better than that."

The strategy group on Thursday also agreed to scrap the radio communications clampdown completely, with the exception of the formation lap.
