Kate Middleton has surprise emotional reunion with midwife who helped deliver Princess Charlotte

Kate Middleton enjoyed a happy reunion with a very special medical professional yesterday.

While visiting the Royal College of Obstetricians and Gynaecologists in the capital on an official visit, the Duchess of Cambridge bumped into the midwife who helped deliver Princess Charlotte in 2015.

Kate spotted Professor Jacqueline Dunkley-Bent as crowds gathered to see the mum-to-be be presented with a certificate to mark her appointment as a patron of the organisation.

Clearly overjoyed by the encounter, Kate later greeted the Head of Maternity, Children & Young People at NHS England with an extremely warm embrace.

The 37-year-old - who displayed her blossoming bump in a smart blue ensemble - tenderly put an arm around Jacqueline Dunkley-Bent, who was equally delighted by the situation.

'It was a surprise and an absolute pleasure to be reunited with Kate again today,' she gushed.

'Supporting families at the birth of their baby - including future kings and queens - is hugely rewarding and we're very grateful to have the Duchess of Cambridge's support for the nursing profession.'

The RCOG is a medical charity focussed on the goal of improving women's health care across the world.

It was founded in 1920 and there are now over 16,000 members around the globe.

Princess Charlotte entered the world on 2 May 2015 at 08:34am in the Lindo Wing of St Mary's Hospital in Paddington.

The two-year-old's brother Prince George, 4, was also born at the facility.

Kate's third child with husband Prince William, 36, is due in April but the expectant mother is currently showing no signs of slowing down her workload.

After her visit to the Royal College of Obstetricians and Gynaecologists, she stopped by Guy's and St Thomas' hospitals to launch a new Nursing Now campaign.

'@NursingNow2020 is a global campaign that aims to raise the worldwide profile of nurses and enable them to take a greater role in health policy decision making,' Kensington Palace informed royal fans on Twitter.
