Venezuelan President Hugo Chavez is due to meet Spain's king in Mallorca for the first time since they fell out at a conference in Chile last November.

The row began when King Juan Carlos told Mr Chavez to shut up after he accused Spain's former prime minister, Jose Maria Aznar, of being a fascist.

The remarks caused outrage and no shortage of diplomatic tension.

Mr Chavez said before he left for Spain he would like to hug the king but also warned he is not about to shut up.

Ring tone

"Por que no te callas?" - the five words uttered angrily by King Juan Carlos who was fed up with Mr Chavez interrupting a summit of heads of state - became the buzz of the Spanish speaking world.

It was even turned into a mobile phone ring tone - dozens sprang up in the days following the outburst.

Millions of people downloaded it as "Why don't you shut up?" became a cult slogan.

It spawned hundreds of jokes and cartoons and was emblazoned across t-shirts.

For his part, Mr Chavez accused the king of impudence and arrogance and immediately said he would review the business of all Spanish companies in Venezuela.

Little came of the threat and ties have since improved, but there is still intense interest in this meeting.
