Update: Robredo is Housing Secretary. http://newsinfo.inquirer.net/794933/hello-maam-leni-duterte-offers-robredo-housing-post-via-phone-call
Gil Ramos, who monitors what’s going on in the Philippines, especially political happenings from the United States where he is based, wrote me his view that it is better that Vice President Leni Robredo is not part of the Duterte cabinet.
In fact, I cannot understand, the fuss by the Mar Roxas- Leni Robredo supporters about the VP not being appointed to a cabinet position. The President is not obliged to give Robredo a cabinet post and he has already explained why — he is concerned about the feelings of Ferdinand Marcos, Jr, the closest opponent of Robredo. There are other reasons like the friendship of his father to late president, Ferdinand Marcos, as well as the support of the Marcoses to him last election.
Duterte is planning to give Marcos a cabinet position after the one-year ban on candidates who lost in the last May elections and it would indeed be awkward for Robredo and Marcos to be working together under Duterte.
