David Cameron goes to a science exhibition and is shown a time machine which can see 100 years into the future. The man in charge invites him to ask any question he likes.
Cameron asks "What will Australia be like in 100 years time"
The machine whirrs and beeps and goes into action and gives a printout, which the man reads
"The country is in good hands under the new Prime Minister, crime is non-existent, there is no conflict, the economy is healthy. There are no worries"
He has another go "What will China be like in 100 years time"
Another print out
"The country will be the world's leading economy and everyone there will enjoy the highest standard of living in the world"
Cameron then asks "What will Great Britain be like in 100 years time?"
The machine whirrs and beeps and goes into action. The man gets a printout, but he's just stares at it.
"Come on", says Cameron "What does it say?"
The man replied, "No idea! It's all in Arabic!"
