Nick Robinson and the importance of correct punctuation

Something else wrong on the internet, though this one is an interesting point of language.

Nick Robinson has omitted a hyphen on his blog and said the complete opposite of what he means as a result.

What he says:

As MPs take a whitsun break, I'm taking a few days to recover from Manchester United's night of glory in Moscow and late night by electioneering in Crewe.

What he meant:

As MPs take a whitsun break, I'm taking a few days to recover from Manchester United's night of glory in Moscow and late night by-electioneering in Crewe.
