Mar.22 (GMM) Red Bull has stepped up the technical row with Mercedes by accusing the German team of breaching a gentlemen's agreement.

Red Bull and Lotus last weekend threatened to protest the results in Australia, due to Mercedes' innovative new 'F-duct'-like solution.

"They are not complying with the agreement of the technical working group," said Christian Horner.

Adrian Newey also told Auto Bild Motorsport: "The FIA has allowed the system, but Mercedes has gone against the gentlemen's agreement of the teams."

He is apparently referring to a meeting last year in which teams informally agreed not to pursue certain technical directions.
