Notwithstanding the bizarre "far right credentials" point:
- Liz Truss (current Foreign Secretary) was SoS for DEFRA under David Cameron.
- Sajid Javid (current Health SoS) was BEIS SoS under David Cameron.
- Grant Shapps (current Transport SoS) was Minister for Housing under David Cameron and later party chairman.
- Brandon Lewis (current SoS for Northern Ireland) was Minister for Housing under DC.
- Ben Wallace (clearly ultra right wing (/s), and SoS for Defence), Minister for Northern Ireland under DC.
I don't think this is an exhausive list, these are just the SoSs I can think of off the top of my head. Your statement is just so untrue it just makes me think you don't know much about UK politics and don't really care enough to even google your "facts".
