I have been following Brexit on the BBC website, for example, this article. They have consistently said it's unlikely that Brexit will be cancelled (at times I think they said "very unlikely"), but given the failure to get the required legislation passed, isn't it the logical outcome, unless there is significant political movement?
Personally, I see little chance of the House of Commons agreeing to an exit deal or to a no-deal exit.
So why does the BBC say it is unlikely? What arguments, if any, have they provided for saying that? Since the first vote on the PM's deal was defeated, I have seen it as the most likely outcome, while admitting I could turn out to be wrong.
Edit:
On checking the latest BBC guide to Brexit, it no longer says revoking article 50 is unlikely. Instead it now says:
The European Court of Justice has ruled that it would be legal for the UK to unilaterally revoke Article 50 to cancel Brexit (without the need for agreement from the other 27 EU countries).
With the government still committed to Brexit, it's very likely that a major event such as a further referendum or change of government would have to happen before such a move.
However, any further delay to Brexit would certainly lead to questions about whether the ultimate destination was going to be a reversal of the 2016 referendum.
It's not totally clear what the process would be. But an act of Parliament calling for Article 50 to be revoked would probably be sufficient.
So there seems to have been a change of tune there.
