The Princess of Wales is set to make an emotional return to royal duty on St Patrick’s Day when she meets the Irish Guards during a solo engagement.

Kate, who is colonel of the regiment, missed the Guards’ celebrations last year after being diagnosed with cancer and apologised last summer for missing a key rehearsal for the annual Trooping the Colour.

Meanwhile, King Charles is expected to meet Canada‘s Prime Minister Mark Carney who has become embroiled in a row with US President Donald Trump over claims Canada could become the 51st state.

Who are the Irish Guards?

The Irish Guards is an Irish Regiment formed on 1 April 1900 by Queen Victoria.

Known affectionately throughout the Army as ‘The Micks’, it was founded in recognition of the acts of courage and bravery performed by Irish regiments during the Second Boer War.

Since then, the regiment has continued to serve in numerous major conflicts and guard the Royal Family.

St Patrick’s Day is the traditional celebration of the Irish Guards where its regiment members are presented with fresh shamrock from the Princess of Wales.

Kate’s letter to Irish Guards after she was forced to miss Trooping the Colour

The Princess of Wales wrote to the Irish Guards last year to express her pride in the soldiers and wish them good luck for the Colonel’s Review.

Kate was unable to attend the event as she was receiving treatment following her cancer diagnosis.

The troops gave their colonel a round of applause after the emotional letter was read out at their barracks.

The letter read: ‘I wanted to write and let you know how proud I am of the entire regiment ahead of the Colonel’s Review and Trooping the Colour.

‘I appreciate everyone trooping this year has been practising for months and dedicating many hours to ensuring their uniforms and drill are immaculate.

‘Being your Colonel remains a great honour and I am very sorry that I’m unable to take the salute at this year’s Colonel’s Review.

‘Please pass my apologies to the whole regiment, however I do hope that I am able to represent you all once again very soon.’

Why today will be particularly poignant for Princess Kate

In her role as colonel of the Irish Guards, Kate will today present traditional sprigs of shamrock to officers and guardsmen at the Wellington Barracks in London.

She will also award long service and good conduct medals to soldiers.

It comes after she was unable to attend the ceremony last year as she was undergoing treatment for her cancer diagnosis.

Despite this, Kate was honoured in her absence as the guardsman gave three cheers for their absent colonel as they read out her letter of apologies for missing the event.

Her return today signals another positive step for the Princess, as she gradually steps up her return to Royal duties.
