We report the detection of WASP-35b, a planet transiting a metal-poor ([Fe/H] = -0.15) star in the Southern hemisphere, WASP-48b, an inflated planet which may have spun-up its slightly evolved host star of 1.75 R $_sun$ in the Northern hemisphere, and the independent discovery of HAT-P-30b/WASP-51b, a new planet in the Northern hemisphere. Using WASP, RISE, Faulkes Telescope South, and TRAPPIST photometry, with CORALIE, SOPHIE, and NOT spectroscopy, we determine that WASP-35b has a mass of 0.72 plusmn 0.06 M$_J$ and radius of 1.32 plusmn 0.05R$_J$ , and orbits with a period of 3.16 days, WASP-48b has a mass of 0.98 plusmn 0.09 M$_J$ , radius of 1.67 plusmn 0.10 R$_J$ , and orbits in 2.14 days, while HAT-P-30b/WASP-51b, with an orbital period of 2.81 days, is found to have a mass of 0.76 plusmn 0.05 M$_J$ and radius of 1.42 plusmn 0.03 R$_J$ , agreeing with values of 0.71 plusmn 0.03 M$_J$ and 1.34 plusmn 0.07 R$_J$ reported for HAT-P-30b.
