Pictured: Duchess Of Cambridge Prepares To Board Helicopter For Return Leg Of £3,000 Flight As Queen Makes Same Trip By £54 Train

Kate (above) was pictured ahead of her return from London's Kensington Palace to Anmer Hall, the mansion she shares with Prince William on the Queen's Sandringham estate in Norfolk. 

Her £3,000 return trip on February 7, which was 110 miles and lasted 45 minutes each way, came a day before the Queen made the same journey from Norfolk to London by train for just £54.90. 

Kate took the Queen's Flight (inset) - used by Royal Family members on official engagements, and paid for from money given to the Queen by the Government to fund her official duties as head of state.
