Britain's Prince Harry

The 30-year-old royal - who is currently touring Australia - will jet back to the UK for the annual event on Sunday (26.04.15), which could also give him the chance to meet his new niece or nephew who is due on Saturday (25.04.15).

While it was initially thought Harry would be absent from the birth of his brother Prince William's second child with his wife, the Duchess of Cambridge, it appears he will now be in the UK over the period the 33-year-old royal is expected to go into labour, reports HELLO! magazine.

Prince Harry will be close enough to attend the race as he is due to fly to Turkey on Saturday to commemorate the Gallipoli campaign with Australian Defence Force personnel as part of the World War One centenary celebrations.

A spokesperson for Prince Harry - who is a Patron of the London Marathon Charitable Trust - said: "Prince Harry's attendance at the London Marathon is a long-standing commitment but was dependent on the finalisation of his programme with the Australian Defence Force and confirmation of travel arrangements to and from Turkey."

He will return to Australia on Monday (27.04.15).
