Hello my name is Alex and I will help you with this. Please note that I am a working Solicitor and may be on and offline as I have to attend Court and meet with clients, even at weekends. As such you may not get an instant response when you reply, but rest assured I will be giving your question my immediate attention upon return You do not need to wait here as you will get an email when I reply.
Yes. If they had a reasonable suspicion that you had committed an offence then they can come in and breathalise you.
I am sorry if this is not necessarily the answer you want and is certainly not the one I want to give you, but I have a duty to be honest.
Can I clarify anything for you about this today please?
