Princess Beatrice and Peter Phillips are the favourites to be named as the godparents of Princess Charlotte when she is christened next month, it has been revealed.

Kensington Palace announced on Friday (5 June) that the month-old daughter of the Duke and Duchess of Cambridge will be christened at the Queen's parish church in Norfolk on Sunday 5 July.

Archbishop of Canterbury Justin Welby is expected to carry out the service, which will take place at St Mary Magdalene Church. He is the reverend that christened Charlotte's two-year-old brother George at the Chapel Royal at St James's Palace in October 2013.

The christening itself will be private affair with only senior royals, members of the Middleton family and godparents and their spouses expected to attend. Some members of the public will be permitted to gather outside.

Following the christening announcement, the question on everyone's lips is who will be the newborn's six godparents?

Back in 2013 the royal couple went against tradition and chose seven of their best friends – rather than foreign royals and aristocrats – to look out for their son George.

This time around William's brother Harry, close friend Hugh van Cutsem and Pippa Middleton are strong contenders with his cousins Beatrice and Peter Phillips being the front runners.

Ladbrokes spokeswoman Jessica Bridge previously said: "With no less than seven godparents for George, it looks safe to say Kate and William will go with a similar number for little Charlotte.

"The early money suggests Princess Beatrice, Prince Harry, Hugh van Cutsem and Mike Tindall will be among those Charlotte will look towards for guidance as she grows up."

Charlotte, who is fourth-in-line to the British throne after her grandfather, Prince Charles, her father Prince William and brother Prince George, was born at St Mary's Hospital in London on 2 May.
