Jane Beechey, founder of the consumer PR specialist that has clients including Friends Reunited, declined to comment on the circumstances of Laird's departure.
PRWeek understands that Laird, who could not be reached for comment, resigned from his director-level post earlier this month.
Laird joined BMA from Barclay Stratton last year before the sale of Barclay Stratton's business to Argyle Consultancies, which owns Kaizo (PRWeek, 19 November 2004).
Wandsworth-based BMA declined to confirm its current client roster. In a statement sent to PRWeek confirming Laird's original appointment last December it listed Tesco, Tate & Lyle, The Banana Group, Lactalis, Mr Kipling and Gonzalez Byass.
At Barclay Stratton, Laird worked for health and beauty clients, including Simple Skincare and Lil-let, and left just 19 months after taking over as CEO.
Laird had joined Barclay Stratton 18 months earlier as a director from Nexus Communications.
He had worked for Nexus owner Courthaven as a board director of Nexus' sister firm Cameron Choat and Partners since 1997 and continued with the group after Nexus and Choat were merged in 1998.
Laird was also head of healthcare at The Rowland Company until 1996, and then marketing communications manager.
