Kate Middleton stuns in beautiful red off the shoulder top

She has been dabbling with more daring outfit choices of late - but the Duchess of Cambridge played it safe tonight in a voluminous red gown at a party held in honour of the Queen's birthday.

Kate, 35, turned once again to her go-to designer Alexander McQueen, in a chiffon maxi dress currently on sale for £1,453, and a pair of Prada shoes as she arrived at the reception alongside husband William.

The couple are attending the sumptuous party at the British Ambassador's residence in Berlin for a belated celebration of the British monarch's 91st birthday at the end of their action-packed first day in Germany.

The Queen's birthday falls in April but official celebrations take place later on in the summer, and the British Embassy in Berlin mark it each year with a party - even in the monarch's absence. 

In a speech tonight, William spoke of his desire for the UK and Germany to remain 'firmest of friends' despite Brexit.

He said: 'This relationship between the United Kingdom and Germany really matters. It is the product of many years of working closely together. It will continue despite Britain's recent decision to leave the European Union. I am confident we shall remain the firmest of friends.' 

William added: 'The United Kingdom and Germany proudly share the same values. Today, we share a fundamental interest in the peace and prosperity of the continent of Europe to which we both belong.'  

This is the second party the couple have attended in the Queen's honour following a lavish soirée in Warsaw on Monday evening, as the 91-year-old monarch continues to delegate public duties including tours to younger members of the royal family.

The royals have been warmly received on every stop of their five-day tour of Poland and Germany so far and, earlier this afternoon, thousands lined the Pariser Platz to catch a glimpse of the royals as they visited Berlin's historic Brandenburg gate.

The couple were cheered as they arrived by around 2,000 people, many in fancy dress, who had stood in sweltering conditions to catch a glimpse of the royal visitors.

Some were lucky enough to chat to the Duke and Duchess when they went on a quick walkabout before posing for a picture with the monument in the background. 

The royal couple spent nearly 20 minutes at the Brandenburg Gate, where they were greeted by the Mayor of Berlin, Michael Muller, and his daughter, Nina.

Earlier, the Duchess apologised to Angela Merkel for not speaking German as she arrived for 'extended' discussions with the chancellor.
