Marko told Austrian newspaper Krone:
โThe fact that the book is being published on the very day Dietrich Mateschitz died is an embarrassment.โ
I am supporting Marko today.
This is today's biggest development...in the latest Horny files ๐
Horner recently claimed that Marko failed to offer condolences following the death of Beverley Allen, Horner's former partner and the mother of his daughter, in June 2025.
Horner said:
โHe didn't even offer his condolences. That wasn't very classy.โ
But, On 21 October, German motorsport publication F1-Insider reported that it had obtained an authentic WhatsApp exchange contradicting that claim.
-A message informing Marko of Beverley's death arrived at 1:53 a.m.
-At 4:22 a.m., a reply was sent in the names of Helmut Marko and his partner, Nicole.
-The reply expressed sympathy for Horner and both families, specifically mentioning his daughter Olivia.
-The message reportedly included the words:
โSo sad, my heart is with your family and Beverley's family. And especially with Olivia.โ
