A second referendum possibly the only way, other than a general election to resolve this issue.

And with it resolved and the will of all the people known?

Nominate Boris Johnson as a Special Envoy, with the power to negotiate a better deal and one the entire parliament should be allowed a (secret ballot) conscience vote to ratify it?
Alan B.

The EU made it clear that it was going to punish the UK for leaving. Given that the UK is the second largest economy in the EU and that a hard brexit would be also be a disaster for the EU, deliberately negotiating in bad faith should be considered a stupid move.

May, should simply begin negotiating free trade agreements with the US/Canada/mexico,Australia/NZ etc and let the EU come back to the bargaining table.

Shadow Minister I don't think she can until they are out of EU, there was something a month or so ago with regard to trump and not being allowed to make agreements

I would be very surprised if a number of countries have not already
been having talks on the QT with Britain.
The travel allowances of Australian trade bureaucrats might make
interesting reading.
