Sergio Perez says his decision to dump a sponsor is final.
Just after Donald Trump’s shock US election win, the Mexican driver failed to see the funny side of a joke made on Twitter by sunglasses sponsor Hawkers about the proposed US-Mexican border wall.
After Perez dumped the brand, Hawkers apologised and announced the formation of a charity in the Force India driver’s name to make up for the gaffe.
But Perez said in Abu Dhabi: "I will not go back to working with them.
"Yesterday we finally broke the business relationship," he is quoted by the Spanish sports daily Marca.
"They proposed a foundation with my name, but I said no. I already have a foundation, but if they want to make one for charitable causes that’s fine with me, but I do not need it," Perez insisted.
