It seems to be the Irish who have ensured that there has been no EU movement on the backstop. So if we crash out with 'no deal' what happens then in respect of the EU border between The Republic of Ireland and the UK? I suppose we have to pay the new fee to go to the Republic - except those of us who have passports for both countries?

Suppose the UK just decided to open the border and ignore it. How would this affect WTO negotiations?

Seriously confused by all this. But assuming the Irish Government has thought it through.
