A young boy has written to Britain's Queen Elizabeth II, asking her to give Ireland back the six counties in the North.

Reese Kilbride (12) says he wrote to the Queen after learning about the 1916 Easter Rising.

"They had the six counties, they didn't give back all of Ireland - so I thought they should give it back", he told Newstalk Breakfast.

He also included some pictures with his letter.

Reese says he got his sister to post the letter in February. And he ultimately got a reply from the British monarch.

His mother, Fiona Dowling, says she did not think anything would come of it.

"I said 'if you want to do that, do it', but not to expect a response", she said.

But last week a letter arrived at their home with the Buckingham Palace logo.

"There was a letter open on the counter and it looked (like) nice paper and...looked official and the next minute I saw the Buckingham Palace logo - and to be honest with you I found it quite hysterical".

In the response, the palace says: "The Queen has asked me to thank you for your recent letter in which you wished to tell Her Majesty that you have been learning about the history of the Easter Rising 1916".

"While it was thoughtful of you to let The Queen know of your views, I must explain that this is not a matter in which Her Majesty would intervene".

It explains: "As a constitutional Sovereign, The Queen acts on the advice of her ministers and remains strictly non-political at all times".
