The bypass hose allows coolant to recirculate within the engine, without passing through the radiator, as it does when the engine is warmed up and the thermostat opens. The bypass hose connects the thermostat housing and the water pump. The water enters the bypass tube through the bypass valve, when such a valve is fitted. The bypass valve is sometimes operated thermostatically; it closes off the bypass hose when a certain temperature is reached. This increases the circulation of the coolant within the engine. Many cars don't need a bypass valve, because there is plenty of coolant going through the radiator hoses due to the thermostat.

yup - pretty much what Google says!
Just allows the coolant to flow whilst the thermostat is closed - as soon as the stat's opened flow through the bypass hose pretty much stops - path of least resistance and all that! Doesn't mean that the hose isn't needed, and it needs to be in good condition as if it goes its a right bugger of a job.
Metro 1275's and the later Mini's didn't have bypass hoses, as they had a sandwich plate in the thermostat which worked in a similar way...

Nope. In fact a lot of people get rid of it since when it fails it's one of the most annoying jobs to replace it on a mini (without taking the head of that is). Just make sure you've got a proper thermostat.
