Department of Defence

Regarding the sale of the Gulfstream Govt. Jet 251, I would like a copy of the informal advice that the Dept. of Defence sought regarding the sale of the Jet from an Irish Aviation consultant in August 2015. This was referred to in the C&AG report regarding the disposal of the Jet in paragraph 8.15 - https://www.audit.gov.ie/en/Find- Report/Publications/2016/Disposal-of-Government- Jet.pdf
