Cousland was travelling to Russia on business when the airport was attacked by a suspected suicide bomber. He had been with CACI for three and a half years, conducting market and site assessments and feasibility studies for retail and restaurant chains and shopping centres in Russia and eastern Europe

CACI’s vice president of location planning Ian Thurman said: “We are organising the service to pay tribute to a much-loved, popular and respected colleague and friend. Since his death we have been overwhelmed by the condolences and tributes which have come into our office. The service provides the opportunity for those who knew Gordon to formally pay their respects and to join us in remembering his life.” 

The memorial service will be held at 3pm at St Mary Abbots Church, 2 Kensington High Street, London W8 4SP on 10 March. CACI has also set up a memorial fund for Gordon’s fiancée Loretta and daughter Elisa.

Thirty-five people were killed and more than 100 injured in the bombing in January.
