Lesley Mahmood is a co-founder of the Save Liverpool Women’s Hospital campaign which opposes the move.
She told BBC North West Tonight: “We’re worried that, one, it’s the thin end of the wedge, but two, where is the room in the Royal?”
She said her group was also concerned about wraparound services at Liverpool Women’s Hospital for newborns, breastfeeding and mental health as well as other facilities for women who need gynaecological surgery.
“Where is all that going to go on the Royal,” asked Mahmood. “And where’s the money and staffing coming from?”
She said she also had concerns about pregnant women classed as “high risk” in the Royal’s accident and emergency department.
“If high-risk women become suddenly ill and they feel they should go to the Royal then obviously there’s long queues for the A&E [there].
“There’s people sitting in chairs who are waiting for a trolley, lying on trolleys waiting for a bed, that’s not an appropriate setting for high-risk pregnant women or high-risk gynaecological women.”
Dr Lemmens said this would not be the case, since for complex pregnancies a “very clear care plan” will be produced in advance, so that women will know “exactly what to do” in a range of scenarios. This may involve going to the Royal or Liverpool Women’s Hospital.
She stressed the woman’s care plan “will not include presenting to A&E at either Aintree or the Royal Hospital.”
