David Cameron insists he can always dream and hope Northern Ireland will get behind England at next year's World Cup.
The Prime Minister offered his congratulations to Roy Hodgson's team after they secured their place at international football's most prestigious competition with Tuesday's 2-0 win against Poland.
But Scotland, Wales and Northern Ireland all failed to progress from their groups.
Mr Cameron told MPs: "I'm sure the whole House will wish to join me in congratulating the England football team for their excellent win last night, ensuring they qualify for next year's World Cup.
"My commiserations to the other home nations, including Scotland, who had an impressive win over Croatia last night.
"But I'm sure now that everyone in the United Kingdom will swing behind the English team."
Pausing while MPs cheered and laughed, Mr Cameron then added: "You can always dream and hope."
