Tired of getting to the airport all hot and sweaty after dragging your suitcase (one of the wheels of which is always wonky) a million miles?

A British company has unveiled the world's first motorised suitcase, which promises to take the strain out of dragging heavy baggage.

The £700 PA case has a motor in each wheel and an "anti-gravity" device which claims to make a 66lb (30kg) load feel as light as 6.6lb (3kg).

Live Luggage, which designed the bag, say it can travel at running speed for half a mile when the batteries are fully charged.

Once you get the motors running, you simply have to tug the handle, and then a device within the bag will centre the weight of the baggage directly over the wheels - which means that there's less pressure on your arms.

And there are even pressure sensors in the handle which can detect how hard you are holding the bag, so, for example, if you have to go up hill, the motors will adjust accordingly.

If the case is accidentally dropped the motors automatically switch off, so it won't run away.

If you're travelling through Heathrow Terminal Five, and are slightly concerned that your beautiful baggage may go walkies, then each case has a laser-etched serial number.

If it is lost, the finder can contact its makers who email or text the owner.
