Mercedes have defended their decision to remove the 'KeepFightingMichael' hashtag branding from the livery of their Formula 1 car.

Ever since former team driver Michael Schumacher's horror skiing crash and brain injuries some years ago, Mercedes have published the supportive message on their car.

However, some fans have noted with dismay that the 2017 silver car does not feature the Schumacher branding.

A team spokesman told German newspaper Bild: "It was removed to free the way for future usage of the message.

"Now, 'Keep Fighting' is an initiative founded at the end of 2016 to encourage people based on Michael's legendary fighting spirit.

"Mercedes and the family of Michael Schumacher will work together on a variety of common activities which will be communicated in time," the spokesman added.

Schumacher won seven world championships before his retirement in 2012.
