Redundancyc

Looking for advice on the redundancy process, I've work for my current employer for 12years , had a new manager start 18months ago and basically we don't get on mostly because he is rubbish at his job and I do challenge him, so for the past month we been having meetings (myself and a colleague) about how unsupported we feel ,I got an email invaitation from him last week inviting us to a "catchup" so we went along thinking it was along the lines of previous catch ups (HR have been present throughout) only to be locked in the office and to be told our jobs are at risk of redundancy, we were both completely shocked especially as we are so short staff at the moment,and walked out of the meeting before it ended. I recieved an email on Monday asking me to attend a meeting as I'm now in the 30 day consulation period yesterday was the first letter I've recieved attached to this was my redundancy settlement which is basic statorary rate when it says in the staff hand book they pay double this , so have they done the correct process and are they allowed to pay basic despite what it says in the staff hand book any advise would be gratefully appreciated
