Oliver Houston, of Shareholders United, said: 'Let's hope this campaign of dirty tricks does not escalate any more. It will only be United that suffers. 'It was shoddy in the extreme to hijack such an important forum as the AGM to try to settle personal grudges in the glare of the public spotlight. This is not healthy for the fans or the shareholders of the company. On the surface this could be a row between two neighbours over a garden hedge. But allowing it to spill over into club business as it has done is a serious matter.'
