Zara Phillips takes time for niece's christening with husband Mike Tindall

Zara Phillips has earlier said she would rather prepare for the Olympics than attend the London 2012 opening ceremony.

But this weekend, the Queen's granddaughter still found room in her busy training schedule to go to the christening of her baby niece.

Three-month-old Isla Elizabeth Phillips is 13th in line to the throne after her sister Savannah, and is the daughter of the Queen’s eldest grandson, Peter Phillips and his wife Autumn.

Zara's husband, England rugby player Mike Tindall, as well as her mother, the Princess Royal, were also in attendance at the christening.

Baby Isla's father, Mr Phillips, 34, is the son of Princess Anne, and met his wife in Montreal in 2003.

They married at Windsor Castle five years later.

Canadian-born Mrs Phillips, 33, a former Roman Catholic, was accepted into the Church of England shortly before their wedding.

Her husband would otherwise have had to give up his right to the throne.
Although he is 11th in line to the throne, Peter does not have a royal title as his mother declined to give her children the HRH title at birth.
