How do you finish a letter to a president or politician? Is it with yours faithfullyvxxQr
Hi

Yours faithfully (or faithfully yours) seem too informal to me. If you really want to impress them, I'd recommend:

I have the honour to remain, Sir, with the greatest respect,

or if it's a woman:

I have the honour to remain, Madam, with the greatest respect,

There are probably multiple variants on this one.

Having said that, I think I have the honour to remain, Sir, with the greatest respect
is perhaps a tad too formal and pompous if you are writing to a politician of your city council.

I'd think it fits best for a letter addressed to a President or royalty. Perhaps a teacher can give you a more suited one for a 'common' politician. Yours faithfully (or faithfully yours) would in that case suffice, I think.
