We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with radius 1.30 ± 0.09 R Jup, mass 1.90 ± 0.08 M Jup, and an orbital period of 1.401 days. Its host is a Sun-like star, with a G5 spectral type and a mass and radius of 0.98 ± 0.06 M ☉ and 0.96 ± 0.05 R ☉, respectively. The proximity of the planet to its star means that WASP-135b receives high levels of insolation, which may be the cause of its inflated radius. Additionally, we report weak evidence of a transfer of angular momentum from the planet to its host star.
