Prominent right wingers engaged in a plot to prevent the Popular Front from taking power. Gil-Robles and other RW leaders put pressure on Manuel Portela Valladares, PM at the time of the election, to proclaim martial law and declare the results of the February election invalid. Declaring martial law would pass power to the army. The plan failed as senior generals didn't believe the government was ready to take power, but the attempt was a clear indication of the seriousness of RW opposition to the Popular Front.
