'Catherine is thrilled by the kind wishes and support': Camilla thanks well-wishers for messages to the Princess of Wales and promises to pass on posters - as the Queen gets back to business with more duties while Charles and Kate are treated for cancer

Queen Camilla was greeted with cheers from delighted wellwishers at an engagement in Shrewsbury today as she returned to her royal duties. 

The monarch was met with dozens of royals fans, who waved Union Jack flags and held signs reading 'I love Queen Camilla', as she arrived at Shrewsbury Farmers' Market in Shropshire today.

Her Majesty met two young girls who had made posters for the Princess of Wales, who was recently revealed she had been diagnosed with cancer, which Camilla promised to deliver for them. She then told them: 'I know that Catherine is thrilled by all the kind wishes and support' 

Camilla also met with market traders as she toured the market which featured a host of food, artisan, jewellery and craft stalls. 

Charles, who is currently being treated for cancer after being diagnosed with a large prostate earlier this year, was seen being driven out of Clarence House in his state Bentley limousine earlier today, although it is not known where the King was going.

It comes after Buckingham Palace yesterday confirmed both royals would attend this weekend's Easter Sunday service in St George's Chapel at Windsor Castle. 

The Queen met with market organisers Jenny and Stuart Jones before touring the historic event which has been held in The Square for almost 20 years

It has grown into one of the best markets in the area with around forty traders regularly setting up stall on the first Friday of the month. 

Her Majesty will also visit the Old Market Hall where she will sign the visitors book, which was also signed by Queen Elizabeth II in 1952, before meeting members of the local Bee Keepers' Association. 

From there Camilla will travel to the recently restored Shrewsbury Flaxmill Maltings, before meeting local volunteer groups. 

These include the Shrewsbury Food Hub, Shrewsbury Interfaith forum, Save our Shropshire and Shropshire Supports Refugees.

Royal aides revealed yesterday morning that the couple would be 'accompanied by other members of the Royal Family', although no further names were given.

The decision for Charles to attend will be viewed as significant given that it suggests the King's doctors are happy for him to be at an event despite his cancer treatment.

The Prince and Princess of Wales and their children George, Charlotte and Louis will not be there as they spend the holidays together after Kate's cancer diagnosis.

The Easter Mattins Service - as it is officially known - which will run for one hour from 10.45am until 11.45am, according to the chapel.

The service will be preceded by holy communion from 8.30am until 9am. There will also be a said eucharist from 12pm to 12.45pm, then evensong at 3.30pm to 4.15pm.
