'It ought' or 'It ought to be'

[TheDevilWearsPrimark]

Is there any need for the 'to be'?

It ought to be obvious.

It ought obvious.

umm....

'Ought it to be illegal to park in a P&T space without a child?'
'Yes, it ought'

the 'to be' in the second sentence is implied.

I suppose yes it depends on context.

Sqounk, Obvious, ought it?

p.s I still want to scrabulous with you, but can't without all my facebook friends/family knowing I Mumsnet. Sorry.

TDWP - there's no need for them to know you mumsnet just because I do... I could be a friend of a friend
