Two men accused of planning to smuggle millions of pounds worth of Class A drugs into the UK in hollow pianos and furniture have been found guilty.
James Ward, 53, of Battersea, and Gary Vian, 45, from Croydon, both in south London, were caught after police bugged Ward's property, the Old Bailey heard.
Ward and Vian will be sentenced for conspiracy to supply on Wednesday.
Jasraj Singh, 39, of Birmingham and Paul Woods, 31, and Terrence Pyne, 49, of south London, were all cleared.
Police heard conversations via a listening device at the Battersea property last February.
They suggested amphetamines, cocaine and other drugs could be brought to the UK from Holland in hollow items made out of MDF.
The prosecution described Vian and Ward as drug dealers on a commercial scale.
