Career
Gallagher"s first WRC rally was the 1975 Royal Automobile Club Rally alongside Norwegian driver John Haugland in a Škoda 120. From the 1977 season until the end of 1980 he partnered Tony Pond in the Triumph TR7 with varying success, mostly in British Rally Championship events. 1981 saw the start of a highly successful pairing with legendary Finnish driver, Henri Toivonen first in the Talbot Sunbeam before they switched to the Opel Ascona 400.
The two parted company in 1984 when Toivonen signed for Lancia and Gallagher joined the Toyota team with another Finn, Juha Kankkunen.
At the start of the 1986 season they parted company, with Kankkunen going to Peugeot. Their last rally together was the 1992 Safari during which they retired from the event due to an engine fire.
Gallagher was absent from the WRC until 1998 when he started competing sporadically and without a steady driver. During this period he sat alongside Ari Vatanen, Thomas Rådström and Petter Solberg among others
After retiring from co-driving, Gallagher became involved as a consultant or clerk of the course on various events including the WRC rallies in Corsica and Cyprus but also in events like Race of Champions.
He worked with the FIA Rally Safety Group in 2001-2005. Gallagher is still active today as a consultant within the WRC.
