OBE caps hat trick of titles for Red Bull boss

Red Bull team principal Christian Horner was left "shocked but very honoured" after receiving an OBE in the Queen's Birthday Honours' List.

Horner, 39, has been recognised for services to motor sport, including leading Milton Keynes-based Red Bull to a hat-trick of Formula One world titles over the past three years.

As a driver, Horner's career first blossomed when he won the prestigious Formula Renault scholarship in 1991. He subsequently competed in British Formula Renault, British Formula Three, British Formula Two and Formula 3000.

Horner's final season as a driver came with Arden in F3000 in 1998, after which he decided to turn his hand to owning and managing the team - at the age of 25.

Horner spent six seasons running Arden, achieving considerable success in later years before being taken on as team principal of the new Red Bull F1 team in 2005.

Aged just 31, Horner was the youngest team boss in F1, and following a difficult first few seasons, success finally arrived in 2010 when Red Bull won both the constructors' and drivers' world championships - a feat repeated in both 2011 and 2012.
