Stolen from elsewhere.
The reason for the club not moving them to BF3 has been well known and discussed for many years. I myself when on the Working Group committee back in 2010-11 spoke to David Martin (head of security at the club) at some length to get UB moved to BF3. The reason is the sight lines for those in the areas beside them. If you are in BF2 or BF4 and wish to watch the match from the comfort of your seat, you cannot see a large area of the pitch due to the UB standing in BF3. This is why they are in BF1, it is the only area where them standing doesnt affect the sight lines of other fans in neighbouring sections. The club turn a blind eye to them standing throughout the game in contravention of the ground rules.
I havent been in the loop on this issue since the WG stood down in 2012, but I cant see that the argument has changed a bit as the fact remains the same. UB can move to BF3 if they sit down, which goes against everything they are about so they have to remain at the end of the stand where they dont disrupt everyone else.
What is the big deal with this anyway? They can expand into BF2 if they have sufficient numbers, which they have never had.
I understand their plea for a safe standing area, and that they would be upset that we are not going to go for that. Personally, I am against a safe standing area, so I am delighted the club have decided against this.
