Hello, | am writing to this subforum as I am searching for replies that must be as much formal as possible (e.g formal discussions in the parliament or in court).

I Would like to address someone formally, actually the person that will give the talk.
So I am thinking something like the following.

Ladies and Gentlemen let me introduce you to the first speaker of today's talk (talk or speech is more formal? or perhaps something better). Could you please rephrase it to sound more formal?

Moreover I need a phrase to use before describing the procedure that will be followed for the discussion.
I was thinking for something like "Even though everyone knows this procedure please allow my describing the procedure one more time" . It is not so good and it does not sound that formal to me.

Could you please help me with the above two subjects?

I would like to thank you in advance for your help and support
BeST Regards
