When will Britain return to being a constitutional monarchy?

I really don't like this president Elizabeth Windsor, all she does is sit there in her special presidential chair and do nothing except from attending the occional tea party and awards ceremony. She thinks she is so clever doesn't she, buying all that bling she has on. That family of hers act like they own the place too, they seem to think that they are all the president of Britain. I am sick to death of all of them and hope Britain demands a referendum to reintroduce Britain to the monarchy once again and get things back to normal. President Windsor can just go to the USA and join the republican party and be their president if she really wants to we just don't want her.
