It's designed to withstand a terrorist attack - but it turns out Barack Obama's bullet-proof limo 'The Beast' has more of a problem with the humble speed bump.
Yesterday as President Obama was leaving the U.S. Embassy in Dublin in his custom General Motors Cadillac, en route to his ancestral home in County Offaly, the £400,000 vehicle got wedged on a ramp.
The car - which has eight-inch thick armour-plating and weighs 8 tons - was leaving the building, when crowds who had gathered heard a loud bang and saw the car come to a swift halt.
It then became clear the impressive vehicle was stranded and Barack Obama was forced to abandon it… though given it boasts its own oxygen supply he must have been tempted to sit it out rather than make the embarrassing walk of shame.
