Talks between the UK Conservative and Labour parties aimed at finding a compromise way forward are due to resume next week.
He said: "I had a good, business-like, meeting with John McDonnell a couple of days ago, and what we have agreed is a programme of meetings next week on particular subjects with the ministers and shadow ministers concerned getting together to talk about things like environmental standards, like workers rights, like security relationships between the United Kingdom and the EU".
However, now in talks between the two parties, the issue of a customs union is thought to be creating a sticking point.
"I don't think this question can be allowed to drag out for much longer", he said.
On the BBCs Andrew Marr Show, the UKs de-facto Deputy Prime Minister David Liddington said the talks must not be allowed to drag on for months.More news: Democrats slam Trump over sanctuary cities threat
"I think the public rightly wants politicians to get on and deal with it".
"It hasn't changed", he said.
One option that was narrowly defeated in the customs union was Ken Clarke's motion for a permanent customs union failed by just three votes earlier this month.
"We need to be very clear in the course of this that we don't end up letting Jeremy Corbyn dictate to us that we stay in a customs union, or we have some kind of second referendum, or stay aligned with the European single market - all of that given to us by Jeremy Corbyn is a recipe for disaster".More news: Cain may not be able to pass US Senate hearings
SNP's Westminster leader Ian Blackford said it would be "unforgivable" for Labour to avoid another referendum on European Union membership, urging Mr Corbyn to stop wasting time and commit to the Brexit alternative.
Jeremy Corbyn also features on several front pages, with The Observer reporting that the Labour leader has been warned that the party will be deserted by millions of anti-Brexit voters if it fails to give clear backing to a second referendum in its manifesto for next month's European Union elections. "We think the public came to a clear view in 2016 with all parties saying your decision will be final", he said.
"If, on the other hand, we do offer clarity and a confirmatory ballot, we could do very well".
The deal includes a break clause that will allow to the United Kingdom to leave earlier if the House of Commons can pass the EU Withdrawal Agreement.More news: How to watch Game of Thrones (Season 8) Online
