Theresa May says concerns have been expressed about leaving the EU without a deal, with calls for it to be ruled out.
She says the best way to rule out a no deal Brexit is to agree a deal with the EU. The only other way is to extend Article 50, something she says the EU is unlikely to agree to without a clear plan of how an agreement can be reached.
When people say the government should rule out no deal, she says they are essentially saying "we should revoke Article 50".
This doesn't respect the Brexit vote, she says.
Others are calling for a second referendum, she says, but "our duty is to implement the first one". She is concerned about the precedent that would set for future refendums.
She says she does not know what Jeremy Corbyn believes regarding this, as he has "not engaged".
