  In this paper we obtain some cosmological solutions that describe the present
period of accelerating expansion of the universe in the framework of a
geometrical gauge scalar-tensor theory of gravity. The background geometry in
the model is the Weyl integrable and we found a class of power law solutions
for the Weyl scalar field when an invariant metric is employed in a power law
expanding universe. We obtain a deceleration and an equation of state
parameters in agreement with PLANCK 2018 observational data for some specific
parameters of the model. The deceleration parameter tends asymptotically to
$-1/2$.
