Queen Elizabeth is chauffeur for Duchess Catherine

Queen Elizabeth drove Duchess Catherine around the Balmoral estate over the weekend.
The 90-year-old monarch was spotted giving the 34-year-old royal – who is married to the Queen’s grandson Prince William – a lift to a family picnic just above Loch Muick on their Scottish retreat.
Both looked relaxed as they took in the beautiful landscape.
The Queen was later seen ferrying the Duchess of Cambridge’s mother Carole Middleton around.
A source told The Sun newspaper: “It’s very unusual for in-laws to be welcomed so warmly into the Royal Family.
“This personal invitation shows how much regard Her Majesty has for the Duchess’ family. I can’t recall them staying at Balmoral before, so this is a real sign of affection.”
Meanwhile, it was previously revealed the monarch is “most relaxed” when at Balmoral.
Sir Kenneth Scott, who worked as the Queen’s personal secretaries until 1996, said: “Balmoral is where she can be at her most relaxed. She stays there until the beginning of October, when she returns to London. She rides in the mornings, drives round the estate to visit tenants, and even goes into the neighboring town, Ballater, from time to time to do some shopping. Once, in a Ballater shop, she met another customer, who said, ‘You look just like the Queen!,’ to which Her Majesty replied, ‘How very reassuring!’
“At Balmoral and at Sandringham she likes to take her guests, including bemused prime ministers, for picnic suppers in a log cabin on the estate. The Duke of Edinburgh cooks the barbecue, and the Queen lays the table and helps clean up afterward.”
