Kate Middleton's bouquet tradition

Britain's Kate Middleton will follow tradition and place her wedding bouquet on a tomb in Westminster Abbey during her marriage to Prince William.

Kate, 29, will copy William's mother Princess Diana and grandmother Queen Elizabeth by laying her flowers on the Unknown Warrior's grave. The tradition was started by the Queen Mother after she married George VI in 1923 and Clarence House has confirmed Kate is expected to do the same on her wedding day to William, 28.

A source told Britain's Daily Mirror newspaper: "Kate thinks the tradition is a lovely one and is very keen to make the gesture. And as William and Harry are both serving officers who have lost friends and colleagues in Iraq and Afghanistan, it will be a very meaningful thing to do."

Meanwhile, the pair's lavish nuptials - which will be watched by an estimated one billion fans across the world - will be a "no budget" wedding according to prime minister David Cameron.

Asked by US news channel CNN if the ceremony would be a "budget" affair in line with the government's mood of austerity, Cameron replied: "No, it will be a royal wedding that the whole country can celebrate."

He also believed William would not only make a fantastic husband but a "wonderful king one day".
