Thank you Sun Lion for the Daily Mail article. For anyone interested, here is the original Sunday Times article, that is behind a paywall:

I agree with the "royal aid" that Harry and Meghan has broken the agreement "upholding the values of the Queen" by getting into the "muddy waters" of US presidential elections. Here is an extract from the Daily Mail article:
Members of the royal family are supposed to be politically neutral, and under the Sandringham accord - agreed in March when the pair quit their royal duties - the Sussexes vowed that 'everything they do will uphold the values of Her Majesty'.
However, according to The Sunday Times, royal aides have said that the couple's comments last week have broken their promise from earlier this year.
'The [royal] family are all wringing their hands, thinking: where is this going and does this abide by the deal to uphold the values of the Queen? The feeling is it's a violation of the agreement,' one source told the newspaper.
The sources say that if the agreement is deemed to have been violated, Prince Harry's chances of resuming his connections to the Royal Marines and other military posts he is said to hold dear could be under threat.
The arrangement the Sussexes have with the royal family will be reviewed after a year by The Queen, the Prince of Wales and the Duke of Cambridge.
I also agree that there is going to be conflicts and issues if Trump does get re-elected and enters the UK for State Visit. This is unless Harry gets "completely airbrushed", which is not likely, because Harry is always the Queen's grandson and her heir's son.
Buckingham palace sough to distance itself from their remarks, with royal sources saying that the monarch had been embarrassed by the comments, asking what the Queen is supposed to say should Donald Trump have another presidential visit.
'If Trump is re-elected and makes another visit here, what is the Queen supposed to say when her grandson and his wife have effectively campaigned against him?' said a source.
A spokesman for the Sussexes said: 'The duke's message is not in reference to any specific political party or candidate, but is instead a call for decency in how we engage with each other.'
On a side note, the next article with the heading "Do Meghan Markle and Prince Harry actually WANT to be stripped of their titles?" is written by the columnist Sarah Vine. She is the wife of Rt Hon. Michael Gove MP, who is currently the Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office. I do sometimes wonder does Mr. Gove have the same view (in private) of Harry and Meghan? However, the Government and Cabinet has not been involved in these matters, because there are more important things to worry about.
