What would you put down as 'common properties then' for example ?
if we can agree that common properties is synonimous with characteristics then the results of a MORI poll might answer your question -
The MORI report found a great deal of resistance to the idea – especially among

be described as “typically British” emerged fairly consistently from all the groups:
• tradition/history; and
These lead us to the criteria for assessing Great Britons.
