Lewis Hamilton has called the imminent verdict on Christian Horner’s Formula One future an ‘important moment for the sport to make sure that we stand true to our values’.

Red Bull Racing’s parent company Red Bull GmbH announced on February 5 that Horner is being investigated following an accusation of ‘inappropriate behaviour’ by a female colleague. Horner denies the claim.

The embattled Red Bull team principal is due to arrive in Bahrain for the first race of the season on Wednesday.

A verdict on whether he remains as Red Bull team principal is expected to follow.

‘We always have to do more to try to make the sport and the environment for people to work in feel safe and inclusive,’ said Hamilton as he addressed the controversy for the first time ahead of Saturday’s curtain raiser in the Gulf kingdom.

‘Any allegations have to be taken very seriously.

‘We don’t know everything that has gone on but it needs to be resolved because it is hanging over the sport.

‘It will be interesting to see how it is dealt with, and the effect that it may or may not have on the sport moving forward.

‘It is a really important moment for the sport to make sure that we stand true to our values.’

Horner has been Red Bull team principal since they entered F1 19 years ago and is the longest-serving boss on the grid.

During that period he has overseen seven drivers’ world championships and six constructors’ titles.

Red Bull have dominated the sport in recent seasons and last year won 21 of the 22 races, with Max Verstappen setting a new record for 10 consecutive victories.

Verstappen, who heads into the new campaign as the favourite to win his fourth title in a row, said: ‘He (Horner) is very important otherwise he wouldn’t have been in that position for such a long time.

Max Verstappen opened up on the potential impact of losing his team’s leader in the long run

‘If your team boss disappears for one of two races, for whatever reason, not much is going to happen because everybody is in their role.

‘Then things will start to be different if one of the leaders is not there anymore, but we are not thinking like that.

‘We trust the process and we have to see what the outcome will be. Besides that, everyone is focused on what happens on track and we are in a good mood to get going again.’
