This one of those things which I can easily get wrong but then, when told the correct answer, I find myself saying "Oh, yes, of course it is!"
i.e. I suspect that if, out of the blue, you'd have asked me for the most southerly point of mainland Britain, I would probably have replied with "Land's End" but, as soon as you'd pointed out that it's actually Lizard Point, I'd have kicked myself and said "Oh, of course!"
Incidentally, remembering that Land's End is the most westerly point of
England, having just been reminded that Lizard Point is the most southerly and knowing that Lowestoft is the most easterly ('cos I live in Suffolk!), I got to thinking about where the most northerly point in England is and, having just googled it, I was amazed to find that I'd never heard of it!
So how many people here would know the answer in a quiz?
