Back-calculation expert RTA CroydonMagsLass 12 Feb 2021 14:01 GMT

Dear members

For a hip-flask defence to driving with excess alcohol - can any member recommend a reliable expert in this area?

Also one who may be able to advise whether a gastrointestinal disorder is likely to affect breathalyser readings? Thanks.

Kindest,
