On Tuesday , she was regal in eye-catching crimson for a state banquet at Buckingham Palace alongside the Queen and the Duke of Edinburgh . Last night saw Mexican First Lady Angélica Rivera on dazzling form for the second day in a row as she dressed up in a floor-length black dress and diamonds for a banquet hosted by the Lord Mayor of London .

There , the glamorous political wife was spotted winking at the royals as she arrived with her husband , before smiling and laughing her way through the ceremony - indulged by an equally cheerful Queen . Ms Rivera , a former soap star , was then squired on a tour of the Royal Collection by a clearly charmed Duke of Edinburgh , with the pair seen deep in conversation as they inspected a saddle presented to Prince Philip during a visit to Mexico in 1975 . Her whirlwind tour also included a solo visit to the set of Downton Abbey alongside the Countess of Wessex yesterday , with her husband spending much of the day at Downing Street instead . But it was for the final evening of her stay that Ms Rivera really pulled out all the stops , arriving at London 's Guildhall in a spectacular floor-length black dress , teamed with a pair of diamond drop earrings and a matching bracelet .

The banquet , which was hosted by the Lord Mayor of London , Alderman Alan Yarrow , and the City of London Corporation , is a state visit tradition , with invitations extended to all visiting heads of state . Ms Rivera , who was presented with a pretty bunch of spring flowers as she arrived , spent much of the evening chatting happily to the Duke and Duchess of Gloucester , who were also at the event , and Mrs Gilly Yarrow , the wife of the Lord Mayor . On arrival , the couple were welcomed with a Royal Salute fired from the cannons at the Tower of London during which a total of 62 shots were fired - the basic 21-gun Royal Salute , plus another 20 because the Tower is a royal palace and a further 21 for the City of London . The Mexican National Anthem was then played and President Peña Nieto was invited to inspect a Guard of Honour before making his way inside . At the end of the banquet , both President Peña Nieto and Lord Mayor Yarrow made speeches - in President Peña Nieto 's case , for the second night in a row .
