Deliberate misinformation?

The BBC are triumphantly reporting, in response to accusations (such as mine) that Gordon Brown claimed "The majority of drivers will benefit from this proposal", the following:

"However Downing Street pointed out that Mr Brown had told MPs at question time on 14 May that "the majority of motorists will benefit or pay no more in vehicle excise duty as a result"

Indeed he did, in May; However on 4 June he said (my emphasis) "If the right hon. Gentleman looks in detail at the proposal, he will see that the majority of drivers will benefit from it". For lazy BBC people you can see this in Hansard (4 Jun 2008 : Column 765).

So now that we see that Gordon Brown did indeed mislead the House of Commons, I ask again - should he not be called to apologise to the House? And should not the BBC with all its resources be able to find out this sort of information - or are they not interested in uncovering a Number 10 lie, after all there must be a piece of Tory sleaze somewhere that could provide a useful headline.
