  After the release of the PLANCK data, it is evident that inflationary
paradigm has stood the test of time. Even though, it is difficult to realise
inflationary paradigm in a particle physics model as the present observations
have ruled out the simplest quartic and quadratic inflationary potentials,
which generically arise in particle physics. We would show that such simplest
inflationary potentials can evade discrepancies with observations, if the
inflaton field is assisted by another scalar during inflation. Moreover, unlike
other multifield models, our model yields no isocurvature perturbations and
negligible non-Gaussianity, making it more compatible with the present data.
Above all, our model can also be realised in the framework of SUGRA.
