Prince William and Duchess Catherine have joined Queen Elizabeth for a tour of Nottingham today (13.06.12).
The royals - who married in April 2011 - have stepped in to replace Prince Philip, who is still recuperating following his release from hospital on Saturday (09.06.12) after being treated for a bladder infection.
Queen Elizabeth travelled to Nottingham by train where she was greeted by the younger royals who are believed to have driven from their home in Anglesey, Wales.
The group met well wishers before going into the Council House to meet the Lord Lieutenants of Nottinghamshire and Derbyshire.
Following a reception in the ballroom, the royal party were due to travel to Vernon Park in Basford to mark a Fields in Trust project which preserves parks as recreational spaces.
As patron of the Queen Elizabeth Fields Challenge, a project supported by The Foundation of Prince William and Prince Harry, the Duke of Cambridge will give a speech later today.
Nottingham City Council leader Jon Collins said: "As the capital of the East Midlands, it's great Nottingham's playing host to this royal visit.
"I'm sure that local people will give the royal party a warm welcome and will be excited about getting the chance to also see the Duke and Duchess of Cambridge as part of the Diamond Jubilee celebrations."
