The royals are again choosing private medical care for the upcoming birth of their second child. And Prince William and his wife Kate's decision to use St Mary's Hospital in Paddington, central London, over public care offered by the NHS was yesterday backed by the Prime Minister. Asked if the royal couple's choice was disappointing, David Cameron said he supports peoples' right to choose treatment options – but also ensured he praised the NHS. Scroll down for video . 'Matter of choice': Prime Minister David Cameron (pictured yesterday during a General Election campaign visit to Norton-sub-Hamdon in Somerset) has backed the royals' choice of private care for Kate's second birth . Private healthcare: The Duke and Duchess of Cambridge leave the Lindo Wing of St Mary's Hospital in Paddington, central London, with their newborn  son Prince George in July 2013 . The Prime Minister, a father of three, told Murnaghan on Sky News: ‘I think it's a total matter of choice for people - what they use and where they have their babies. ‘All I hope and pray for is there'll be happy, healthy news for that wonderful couple and for the whole country. The NHS is superb and I've seen that in my own life in so many different ways. ‘But I believe in choice, I believe in people being able to do what they want to do, and as I say I've only got one thought about the royal baby which is a happy and healthy arrival.’ The baby is already believed to be late – and will officially be overdue if Kate has not given birth by May 1. Even the 33-year-old royal herself has said the baby is due in mid to late April. Anticipation: Barriers for the media outside the Lindo Wing on Saturday, which has a separate entrance from the rest of the hospital, making it easier to provide security and a measure of privacy to the couple . The Duke and Duchess of Cambridge’s first child, Prince George, was born at the Lindo Wing of St Mary's Hospital nearly two years ago in July 2013. The wing has a separate entrance from the rest of the hospital, making it easier to provide security and a measure of privacy to the couple, who could receive a visit from the Queen. The public part of the hospital has seen a surgical ward closed to new admissions for the last 11 days because eight patients were found to be carrying a potentially dangerous microorganism. The hospital said today that three of these patients developed infections and have since recovered after treatment with antibiotics. It added that a ‘deep cleaning’ of the ward is underway and enhanced screening is being put in place. Mr Cameron's son Ivan, who had cerebral palsy and epilepsy, tragically died aged just six at the hospital in February 2009. And in his conference speech last October, the Prime Minister said he knew 'better than most' how much the NHS meant after the care it provided to his child.
