George Russell has appeared to hit out at Red Bull boss Christian Horner as he warned there were "mixed agendas" in the porpoising debate. Russell has warned teams who are competitive clearly "don't want change" as he claimed some were "prioritising performance over driver health".

His comments come just days after Horner slammed Mercedes' calls for regulation changes. Speaking to Sky Sports, Russell said: "It clearly is a safety concern. There's obviously a lot of mixed agendas out there from different teams, different drivers.

"Because teams who are competitive, they clearly don't want change. But every single driver at some point has come out and said how bad this has been. So it's a bit of a shame to see some try to prioritise performance over driver health as such."
