Over 14 Prime Ministers have served Queen Elizabeth in her reign but the one with the most blunders is reportedly Prime Minister Tony Blair. He served the Queen from 1997 to 2007 and he was also the Leader of the Labour Party from 1994 to 2007.

According to Daily Express, the Prime Minister once had an embarrassing moment when he took the seat that was supposed to be for Prince Philip, the Duke of Edinburgh and the Queen's husband. This happened during the Jubilee lunch in 2002.

Apparently, Blair didn't realize that he was sitting on the assigned seat for the royal until a few moments later. Realizing his error, PM Blair stood up and moved six seats from his across the row. Prince Philip, however, did not take any offense to the blunder though it was rumored that he once described Blair and his wife as rude people. Instead, Prince Philip was laughing as he walked over to Queen Elizabeth to take the spot next to her.

A spokesman for the event said that there was a bit of mix-up with the seating during the Jubilee lunch since the guests came in the hall in the wrong order. But they all had a good laugh about it after PM Blair said out loud, in his self-deprecating humor, that he was in the wrong seat.

Meanwhile, the Telegraph reported that Queen Elizabeth and Blair had an uneasy relationship all throughout his term as Prime Minister. Though they are devoted Christians, Blair apparently shared just few things in common with Her Majesty, which would have helped build a rapport with the royal.

The report stated that Blair is quite used to city life and loves sports like football and tennis. The Queen, on the other hand, loves the countryside and hunting or fishing as her sport. Thus, it's been said that Prime Minister Blair would avoid going to the Queen's country home in Balmoral, Scotland as much as possible so that he won't have to hunt. If he were to visit the royal, he would reportedly spend just a day at the old castle.

Sources said that Queen used to air her concerns to confidantes over Blair's policies in government. He, on the other hand, has a different belief when it comes to the monarchy,

Despite their differences in interests and takes on issues, no animosity exists between Queen Elizabeth and Blair. Their weekly meetings have always been cheerful and courteous, according to royal sources.
