We show that the reduced von Neumann algebras of the free orthogonal and freeunitary quantum groups have the Haagerup approximation property. Using thisresult and a Haagerup-type inequality for these quantum groups due to Vergnioux(J. Operator Theory 57, 303-324 (2007)), we also show that the reducedC$^\ast$-algebras of the free orthogonal and free unitary quantum groups havethe metric approximation property.
