Lewis Hamilton has confirmed he has held "positive" talks with Mercedes over his future.

Speculation surrounded Hamilton for the majority of the 2020 Formula One season as he won a record-equalling seventh drivers' championship.

The Briton returned to Mercedes for this campaign but only signed a one-year deal, meaning he is again out of contract at the end of the year.

Hamilton is engaged in a gripping title tussle with Max Verstappen, who leads the championship for the first time in his career.

P7, P15 and P2 finishes across the past three races have opened up a 12-point gap at the summit.

Only in 2016 (five, twice) has Hamilton gone longer without a victory since 2014, but the Silver Arrows remain keen to keep their prized asset on board.

"[There is] not a lot to say too much on, but we have had discussions and things are positive," said Hamilton ahead of the Styrian Grand Prix.

Should he wish to commit to Mercedes, Hamilton is assured of a seat, having claimed 98 wins and 100 poles in his F1 career – two records.

Team-mate Valtteri Bottas is less secure, with Mercedes' team principal openly discussing the option of promoting George Russell.

But Hamilton said: "Valtteri is my team-mate now. Both of us have had ups and downs in our careers, but he is a fantastic team-mate and I don't necessarily see that it needs to change.

"We have worked well for many years. Valtteri has been my best team-mate overall, and when I say team-mate it's not just driver performance, it's about team morale and how you work in the team-mate environment."

On Russell, who drove for Mercedes in Hamilton's place late last season, the reigning champion added: "He's not my team-mate currently, so [there is] no need to say anything on it."
