The population of Port Sunlight is 1,450.
Port au Port East's population is 608.
I can't see how it could have been because it is in Bebington and Port Sunlight has a very definite border about a third of a mile away. Having said that, Port sunlight is very close - cross the road and round the corner, so it might have been 'described' as being in Port Sunlight. Port Sunlight had its own sports facilities originally and as far as I am aware has never claimed to extend to ownership of The Oval. HTH
