Reebok has waded into the controversy over Donald Trump's well meant, but probably ill-advised compliment to France's First Lady.

The Massachusetts based sportswear company, which is now best known for its sponsorship of mixed martial arts and hard core fitness training, has offered the US president a cut out and keep etiquette guide, the Independent reported.

Mr Trump was caught on camera saying to Brigitte Trogneux, the wife of French president Emmanuel Macron: "You're in such good shape..beautiful."
