In recent experiments at GANIL and GSI, we studied the decay of $^{45}$Fe, according to theoretical predictions one of the most promissing cases for 2p radioactivity. Our results show for the first time clear evidence of this new radioactivity. In another experiment at GANIL, 2p emission was observed from excited states in $^{17}$Ne. In these complete kinematics measurements performed at the SPEG facility of GANIL, the angle between the two protons has been measured evidencing a $^{2}$He emission pattern. Both results will be presented and future studies are discussed.
