Other issues following Dr. Chua's resignations

Now that Dr. Chua Soi Lek has resigned all his political positions, the issues that follow are who would fill in the vacancies and whether the filling-up process would trigger off power struggles within MCA. Not less important are the questions of who did the video recording and its initial public distribution which is certainly a criminal act by law and whether he/she/they who committed such a criminal act has to do or links with MCA's internal power struggles and, if not, what are his/her/their motive or motives of committing the obvious crime of manufacturing and circulating pornography with high technology ?
