Brother re-invited himself to the wedding

Hey


Long story for this but I was supposed to get married in March 2020 in Vegas. There was a family holiday already booked in before we got engaged. Once we were engaged we thought we may aswell add a wedding onto the Vegas trip to make it simple. We didn't think there would be any drama but then I found out that my mum had invited my brother to Vegas, a brother I don't speak to and haven't had a relationship with for years. I ended up calling him and stating that, sorry but we're not inviting people, we're simply getting married when we are on holiday. Even our best friends wouldn't be there. He was annoyed but nethertheless we held our stance.
We did, however, invite him to the local reception which was essentially a big party for everybody afterwards. He told me in person that he would rip up the invite if I tried to give it to him as if he wasn't invited to Vegas he wasn't going to the party. We ended it by agreeing he wouldn't come. Then covid happened.
We're now due to get married with a small group locally and a couple of months ago invited family again. We invited my brother again who shouted down the phone that he wouldn't come if his three kids weren't invited. We're doing a child free event.
Now I've just been told by my mum that my brother has now done a u turn and wants to come. He's not told me but is simply planning to turn up. I told my mum in no uncertain terms that his place is no longer available and he cannot come.
Now.. I think he's going to turn up. Very few people (other than my mum) like him. I don't want him there and invited him out of politeness. My FH doesn't like him and is ready to physically remove him if he arrives. Any advice on handling this?
