I dont mean the referendum per se but more the complete and utter lack of any recognition or acknowledgement of what might happen or need to be put in place if 'leave' won?

Now whatever side you were on, or neither side, we have legal challenges here there and everywhere, no idea about what is right for the UK if we do eventually come out, how it will affect our rights as citizens.

He has achieved complete and utter breakdown in the UK.

People are letting him off the hook too easy for the mess the country is in.

A knighthood for delivering us from the tyranny of the EU.

News just in; no breakdown in the UK.

Business as usual, people getting on with their lives shock.

How can anyone be responsible for something that might or might not happen in the unseen unpredictable future?

No.

Anyway like Osborne he is now making more money for doing one speech in the US than he earned in an entire year as PM.

Speaks volumes really - they were both only really in politics for the money they could make after leaving politics.

He'll do wot most ex tory politicians seem to do, join a merchant bank, and make loadsa money from insider knowledge .......

What consequences is the OP expecting him to face?

He promised a referendum in the Tory manifesto and delivered that manifesto when a Conservative government was returned. He followed the will of the British people!

The utter mess we find ourselves in is all down to us, the great British public. This is all the will of the British people!

The media hardly ever mention his role in the utter shambles, they are far too busy re-writing history in order to blame Labour and Corbyn for the leave vote, despite 64% of Labour voters voting remain compared to only 42% of Tory voters,

42% of Tories compared to 64% of Labour voters voted remain, and yet all we hear from our 'impartial' media is how Corbyn, the man who was NOT the leader of the remain campaign, or even the leader of Labour's remain team, or even the leader who though a referendum was a good idea, .... Failed to get HIS message across to Labour's voters/supporters and that's why leave won,

While the man who WAS the prime minister, and who got panicked into promising a referendum in order to stop the massive hemorrhage of Tory support to Ukip,

The man who was.... the leader of the country, his party, the remain campaign and the man who gave us the damned referendum, not only FAILED to convince even HALF of his voters/supporters to agree with him (42%) but he also, with staggering arrogance and utter incompetence FAILED to make preparations for what happens if he loses, Is allowed to cowardly run away into the sunset leaving the chaos he created behind him and is given a 'free pass' by the media who concentrate the force of their propaganda on Corbyn.

But hey, those of us who point out the blatant media bias are 'paranoid'.

He failed.
He resigned.
He stepped down.

What else is he supposed to do?

He failed, he ran away,

Yes. Better than failing and staying

Had he had the leadership quality and humility to consider the possibility that he might lose, he could have put contingency plans and a strategy in place to deal with such an eventuality,
he could have had an exit negotiating team on standby perhaps even with himself as the head, under such circumstances he could have emerged from this debacle looking like a competent and strong leader rather than what he ended up looking like, an embarrassing (word I can't use) who has made us a laughing stock before the entire world.

Under such circumstances he could possibility have kept his job.

No. But, like Tony Blair, the history books won't be kind to him because of one monumentally poor decision.

I daren't go out of the house lest I be assaulted by drama queens.

A tiny bit of the world even cares what this little tit of a place does.

Somewhat different though.

Delivering on an election promise
vs
Entering an unfounded sexed up unjust war.

Totally agree with OP.
Whether Remain or Leave, those leading the campaigns were only spokespersons for that side. So on June 24th there was no point in saying to Gove/Johnson et al "So, what now boys?"
Who WAS..and IS responsible for delivering the outcome? The bloody government!
Hence Cameron should not have been a spokesman for either side because he had responsibility for seeing the result through... which he promptly relinquished!
I voted Remain, but I put the current mess down to him.

But he shouldn't have kept his job, so he did the right thing. He took a risk and lost, that's life.

However, what he did do was lead a government in coalition and in the eyes of the general public, did such a good job of it voted the conservatives into a majority.

I'm sure other parties would like a strong leader that could achieve that for them.

Wouldn't go that far, he increase his party's percentage of the vote by 0.8% from 2010, and that still only gave him 36.9% of the vote. That's hardly a ringing endorsement.

He got them a majority, that is a ringing endorsement.

Politicians hardly ever have to face serious personal consequences for policy failure or telling lies to get into power.
It is one of the many failings of our system.
I would happily see them go to prison.

I would think he'll have sleepless nights for years to come - going to bed knowing the absolute chaos and carnage that he has inflicted on this country.

Perhaps I'm being too generous in thinking that he has a conscience of any kind.

He promised a referendum and went charging in with little thought or planning. Totally and utterly irresponsible but probably par for the course for the Bullingdon Boy, Pig Poker.

Why would David Cameron go to prison?

Obviously not. The fault is with the people who voted Leave, and the people who told lies to them. They voted for a collection of halfbaked ideas and lies, after the issues raised had been clearly laid out for them. They also believed people who told them we had a strong negotiating hand, when what we will get, is entirely down to what each EU state will give us. They also had no plan themselves , assumed they would lose , and ran away when the enormity of what they had done hit them. Its no wonder no government can tell voters what they will now get. We won't know , probably until the mid 2020s. Thats what happens when you jump off a cliff - if you don't believe in experts , the consequences only become apparent when you reach the bottom.

Nor could Government work out, in advance, what thedetailed impacts would be for the multiple possible options. It would likely be a nugatory exercise, and would have made Leave argue that the government was spending public money, building the remain case. Leave also had zero plan for anyone to look at the implications of, so there was no one case to explore in detail . . And the leave voters ignored all experts and projections anyway, so further work wouldn't have had any impact on them.

Cameron's government couldn't determine how things should be done in advance legally - without someone raiisng the legal issues in court. His legal assumptions were, as May, and government lawyers, suggested, - that government could act on its own. Nor would any PM want Parliament setting limits on their negotiating position, or to open the door to the Lords holding the process up, for months, or years. You wouldn't explore that legal process, until forced to by a court case. You don't test what works for you, incase the lawyers change what works for you. The current legal mess is largely caused by the anti-leave camp trying to derail the proces, and , Liberals. Labour, and the SNP , manouvering for political advantage, so they can blame the government for, when Europe rejects them.
