Another way to look at the numbers from the first ballot to this one:
First Ballot 12780 ballot papers; 9514 votes yes
Latest ballot 10220 ballot papers; 5751 votes yes
So, an admitted 2560 fewer ballot papers (membership down 20%) and 40% fewer voting yes.
Doesn't look good for BASSA, I predict BA do very little - the next move is for Unite/BASSA and for BA to yawn.
