DUBLIN (Reuters) - There is still a good bit of work to do on the post-Brexit Irish border ‘backstop’, Ireland’s Prime Minister said on Tuesday, expecting a country with as “proud” a history as Britain to keep its written commitments to keep that border open.

“All we are asking is that the United Kingdom honor the commitments it has already made in black and white in the year gone by and I’m sure a country like the United Kingdom, with its proud history, would want to do no less,” Leo Varadkar told parliament.
