How Likely will I be Allowed an Elective C Section in the UK?

Sarah

During my labour with my first baby, we had a placental abruption. I ended up with an emergency C section thank God and my daughter was absolutely fine. Fast forward 6 years and I'm 22 weeks pregnant with my second baby. The thought of going through that again is absolutely terrifying me. On weds I meet with my consultant and my midwife tells me this is when I should discuss the upcoming birth. I really want an elective C Section this time. How likely are they to agree?
