Prince William, Kate Middleton's secret conversation decoded

An intimate moment between Kate Middleton and Prince William have been explained by an expert.

The Prince and Princess of Wales' secret conversation at the cathedral has been decoded by a lip reader.

The royal family put on a united front to honour the late Queen during her Platinum Jubilee celebrations. After the service, the Kate and William were spotted chatting on the steps of the cathedral as they awaited their car to take them to the Guildhall for a lunch reception. 

A lip reader has disclosed the couple's exchange, which included clear instructions from Prince William to Princess Kate, reports Mirror Online.

According to lip reading expert John Cassidy, as they emerged onto the steps, Kate remarked on the service saying: “It went very well, very well” with William replying: "Yes, perfect."

Afterwards, William could be seen waving to the crowd saying hello, and Mr Cassidy says the prince then turned to Kate and said: "Wait for that to move, then we can go."

Meanwhile, a body language expert who looked at the couple at the same event believes the Prince of Wales gave Prince Harry the "opposite of an acknowledgement" and a "barrier gesture".
