Abstract
We estimate the electron and neutron electric dipole moments in the focus p oint scenario of the minimal SUGRA model corresponding to large sfermion ma sses and moderate to large tan beta. There is a viable region of moderate f ine-tuning in the parameter space, around tan beta similar or equal to5, wh ere the experimental limits on these electric dipole moments can be satisfi ed without assuming unnaturally small phase angles. But the fine-tuning con straints become more severe for tan beta >10.
