  We report the possible discovery of multiple gravitationally-lensed images of
QSOs with angular separations on arcminute scales. The QSOs were selected from
the completed 2dF QSO survey as having redshifts and optical colours which are
statistically consistent. In this paper we present higher-quality optical
spectra of the candidates and discuss the likelihood of their genuinely being
systems lensed by massive clusters of galaxies. From a comparison of the
spectra it appears that up to six pairs of QSOs may be lensed multiple images,
although the true number may be less than that and further observations should
be undertaken to amass more evidence and to detect the lensing clusters. Two of
the candidates may be associated with low redshift clusters of galaxies.
