  V1247 Orionis harbours a pre-transitional disc with a partially cleared gap.
Earlier interferometric and polarimetric observations revealed strong
asymmetries both in the gap region and in the outer disc. The presence of a
companion was inferred to explain these asymmetric structures and the ongoing
disc clearing. Using an extensive set of multi-wavelength and multi-epoch
observations we aimed to identify the origin of the previously detected
asymmetries. We have observed V1247 Ori at three epochs spanning $\sim678$ days
using sparse aperture masking interferometry with Keck/NIRC2 and VLT/NACO. In
addition, we search for signs of accretion through VLT/SPHERE-ZIMPOL spectral
differential imaging in H$\alpha$ and R-band continuum. Our SMA sub-millimetre
interferometry in 880 $\mu$m continuum and in the CO(3-2) line allows us to
constrain the orientation and direction of rotation of the outer disc. We find
the L'-band emission to be dominated by static features which trace
forward-scattered dust emission from the inner edge of the outer disc located
to the north-east. In H- and K-band, we see evidence for a companion candidate
that moved systematically by 45$^{\circ}$ within the first $\sim$345 days. The
separation of the companion candidate is not well constrained, but the observed
position angle change is consistent with Keplerian motion of a body located on
a 6 au orbit. From the SMA CO moment map, the location of the disc rim, and the
detected orbital motion, we deduced the three-dimensional orientation of the
disc. We see no indication of accretion in H$\alpha$ and set upper limits for
an accreting companion. The measured contrast of the companion candidate in H
and K is consistent with an actively accreting protoplanet. Hence, we identify
V1247 Ori as a unique laboratory for studying companion-disc interactions and
disc clearing.
