Her majesty called the US president’s bevy of choppers “over the top”, meaning the Secret Service had to rethink their plans to land about six aircraft in the 300-year-old gardens of her main residence during his tour of the UK this week.
She said only three helicopters, including the president’s personal aircraft Marine One, could land on the lawn when Mr Obama, 54, and his wife, Michelle, 52, came for dinner with the Queen and Prince Philip to celebrate her 90th birthday.

One royal source told the Daily Star Sunday: “It was a write-off and the Queen was not amused.”
An insider said US aides refused to change their plans on security grounds but came around to the Queen’s wishes eventually.
They said: “Various US aides said that wouldn’t be possible.
“They said they needed to be within reach of the president at all times.
“They also wanted guards posted inside the dining hall when he had lunch with the Queen.
“But Her Majesty refused to back down and said, ‘three helicopters only’.
Prince Philip drove the Obamas and the Queen from the lawn to the castle
“She rarely imposes her will but when she does people listen – it just took the US Secret Service agents a little time to realise that.”
Yesterday, Obama took part in a question and answer session with young people at Westminster’s Royal Horticultural Halls where he thanked the Queen for lunch the previous day and said how “adorable” Prince George was when he went to Kensington Palace for dinner with Prince William, Kate and Prince Harry the evening before.
It came the day after he urged Britain to remain in the European Union (EU), prompting a backlash from British politicians saying he should stay out of it.
A fleet of US F-22 Raptor combat jets were on standby to shoot down any potential threat.
