Britain's Prince William is set to propose to Kate Middleton this Christmas.
The 26-year-old royal is reportedly planning to ask Kate to marry him at the end of the year, once he has completed year-long military secondment.
Ingrid Seward, editor-in-chief of Majesty magazine, said: "An announcement could be made maybe this Christmas, for a wedding next year. An engagement will happen in a moment and there is a possibility of Christmas or, if not, February.
"But as the pressure mounts on Kate, something will have to happen. Her profile is being raised and this is how they are dealing with girlfriends now. They are being included more so that they know the ropes. Next year will be a far more stable one for William but a wedding will all depend on the royal family's diaries.
"It is not very romantic but it will have to be fitted alongside other possible royal engagements."
It has been claimed the pair - who have been dating on and off for five years - could marry in St. Paul's Cathedral or Westminster Abbey, which are both in London.
Kate's profile has been raised significantly in the past year after she attended several royal events, fuelling reports the 26-year-old has been accepted into the royal family.
One royal source said: "It is a case of ?when' not ?if'. William knows he has to propose to Kate. Their relationship is lengthy by royal standards.
"Her more high-profile appearances are a clear sign that it is now only a matter of time."
