Birmingham have had their transfer embargo lifted by the Football League.
The Blues have been unable to bring players to St Andrews since being placed under embargo in March for not filing their 2010/11 accounts in time. Birmingham owner Carson Yeung was arrested in June on money laundering charges and is due to face trial in Hong Kong in November.
Acting club chairman Peter Pannu said in a statement: "We are pleased that the hard work of those at the club and the Football League has paid off and that the financial prudence put in place since Carson Yeung's arrest has been recognised. Despite the lifting of the embargo, we still need to ensure that this financial prudence remains in place going forward."
