Prince Harry and Meghan Markle held hands as they appeared to support each other after a moving service for the Queen at Westminster Hall.
Today, the Queen's coffin left Buckingham Palace for the final time and went to Westminster Hall, where a 20-minute service was led by the Archbishop of Canterbury accompanied by the Dean of Westminster. During the service, the senior royals stood in formation facing the coffin on its purple-covered catafalque, which was flanked with a tall, yellow flickering candle at each corner of the wide scarlet platform. The King and Queen Consort stood together a metre or so apart, with Princess Anne and Vice Admiral Sir Tim Laurence behind them, then Prince Andrew alone, and in the next row Prince Edward and Sophie Wessex.

Behind them were the Prince and Princess of Wales, William and Kate, with Harry directly behind William and Meghan behind Kate.
At the end of the short service, Harry and Meghan tightly gripped each others hands as they left Westminster Hall - while most of the other royal couples in the procession party walked side by side not touching.
The only ones that did follow Harry and Meghan's lead were the Queen's granddaughter Zara Tindall and her husband Mike Tindall.
Earlier today, King Charles and his three siblings, Andrew, Anne and Edward and the Queen's grandsons Peter Phillips, William and Harry, who stood shoulder to shoulder, escorted the coffin from Buckingham Palace.
Also taking part in the procession were Anne's husband Vice Admiral Sir Tim Laurence, the Earl of Snowden - Princess Margaret's son - and the Duke of Gloucester - a cousin of the Queen.
The new monarch, Anne, Edward and William were all in military uniform for the special occasion, with tens of thousands of people lining the streets along the route, but Prince Harry was in a morning suit.
This is because he is not a working member of the Royal Family, which also meant he was unable to salute during the procession along with his other family members who were in military dress.
Earlier, the Queen Consort Camilla accompanied Kate Middleton in a car to get to the service while Meghan sat in a different car with Sophie, Countess of Wessex.
Kate was captured looking down into her lap, as she passed the mourning crowds in London. Meanwhile, Meghan looked completely heartbroken.
Now up to 400,000 people are expected to brave a 12-hour wait on the banks of the Thames to catch a glimpse of the Queen's coffin as she lies in state for four days ahead of her funeral on Monday.
Today's procession to Westminster comes after there were emotional scenes last night when the Queen's coffin was brought back to London from Edinburgh.
The Queen's grandchildren, including Harry and William - the new Prince of Wales - and their wives Meghan and Kate, were among members of the royal family paying their respects to the late monarch by witnessing her coffin’s arrival at Buckingham Palace.
