Mike Phillipson, MD at the agency's Leeds-based parent company Propaganda, denied the agency's hand had been forced by the resignations and said the decision to close the office was purely a 'commercial' one.
The pair, who said they had resigned at the end of July, are working their notice periods. In a statement Phillipson said the closure had come about because principal clients such as Seabrook Crisps and Dr Oetker were based in the North.
Sources cited disputes with Propaganda as the principal reason for Brignell and Owen's exits. This was denied by Phillipson.
Revolver's London office was reduced to three staff in June, prompting talk of closure (PRWeek, 16 June).
Founder Martin Ballantine, who sold the then 14-strong agency to Propaganda in 2004, left last year, while managing director Trudi Smith quit in January.
