The survivors' group of the Grenfell Tower fire has written to Mercedes boss Toto Wolff to ask the reigning Formula One champions to end their sponsorship deal with building materials company Kingspan.
Kingspan made some of the insulation cladding used on the refurbishment of Grenfell Tower, which caught fire on June 14, 2017, killing 72 people. A public enquiry found Kingspan continued to supply cladding despite tests showing they burned "like a raging inferno" when exposed to fire.
The public enquiry also found company executives ignored customer safety concerns over the cladding.
This week Mercedes named Kingspan as an official partner of the team, meaning the company's name and logo will appear on the car at the Saudi Arabian Grand Prix.
