Fernando Alonso has emphasised that he will remain with McLaren until his contract expires at the end of the 2017 campaign.
Alonso returned to McLaren ahead of the 2015 season on a three-year deal, though was non-committal after the Japanese Grand Prix when pressed on his future.
Ahead of the Russian Grand Prix, and following a sequence of messages on social media, Alonso has re-iterated that he will be part of McLaren for the next two years.
"[I am] staying [for 2016], yes, and 2017," he said during the pre-race press conference at the Sochi Autodrom.
Doubts over Alonso's future were fuelled in Japan when he criticised his 'GP2 engine' over the team radio during the race, as he was powerless to prevent rivals from sweeping past.
Alonso believes that Formula 1 should not broadcast radio messages to the public during races.
"Obviously we have been all season very positive, about the team and about the car, we faced some difficult times, some tough times, all the team and what you talk on the radio should remain private because you are talking with your team, not publicly," he said.
"I think publicly, as I said, we have been very, very positive all the time. You know sometimes it’s normal and understandable, talking to the team, you know the level of frustration and the level of commitment that I have for racing and Jenson [Button] has for racing as well, when you are battling and you cannot hold anyone behind and you are losing positions is normal.
"But as I said, this is a very unique sport, that we have a microphone in our helmet and it goes live on television. Imagine in NBA or football players or something like that what we can find. This is normal and it’s just talking to the team, it’s understandable the frustration with the car."
