  We present results based on follow-up observations of the Type II-plateau
supernova (SN) 2013ej at 6 epochs spanning a total duration of $\sim$37 d. The
$R_{c}$-band linear polarimetric observations were carried out between the end
of the plateau and the beginning of the nebular phases as noticed in the
photometric light curve. The contribution due to interstellar polarization
(ISP) was constrained by using couple of approaches, i.e. based upon the
observations of foreground stars lying within 5\arcmin\, and 10$\degr$ radius
of the SN location and also investigating the extinction due to the Milky Way
and host galaxy towards the SN direction. Our analysis revealed that in general
the intrinsic polarization of the SN is higher than the polarization values for
the foreground stars and exhibits an increasing trend during our observations.
After correcting the ISP of $\sim$0.6 per cent, the maximum intrinsic
polarization of SN~2013ej is found to be 2.14 $\pm$ 0.57 per cent. Such a
strong polarization has rarely been seen in Type II-P SNe. If this is the case,
i.e., the `polarization bias' effect is still negligible, the polarization
could be attributed to the asymmetry of the inner ejecta of the SN because the
ISP towards the SN location is estimated to be, at most, 0.6 per cent.
