Sheikh Abdul, a member of Bahrain’s royal family, appointed Buchanan this week, as negotiations for a bid to save Leeds from administration continued.
A spokeswoman for Brewin Dolphin Securities, which has been appointed by Sheikh Abdul to advise him on any possible deal, would only say that a PR firm had been selected, but no formal agreement had been reached.
A Buchanan spokesman said: ‘We have been appointed by a company that represents Sheikh Abdul. The sheikh is involved in ongoing discussions with the club.’
Last month, Leeds announced that the club could soon be forced into administration after talks with creditors to restructure its debt of almost £80m failed.
The club, which is currently languishing in the Premiership’s relegation zone, failed to secure finance for debt restructuring in November.
In October, Leeds executive chairman Professor John McKenzie confirmed the club had replaced Binns & Co with Holborn PR as its financial adviser (PRWeek, 3 October).
