British Prime Minister Theresa May has said she will set out a plan for the UK, including the right deal for Brexit, over the coming weeks.
Speaking on Sky News, Ms May said government thinking on Brexit is not muddled and time is needed to consider issues before triggering divorce talks.
"Over the coming weeks, I'll be setting out more details of my plan for Britain, yes that's about getting the right deal for Brexit, but it is also about economic reform ... It's about getting the right deal internationally but it's also about a fair deal at home," she said.
She denied the claims made by the former UK ambassador to the EU who voiced concerns to her predecessor David Cameron in talks before Christmas that she risked heading for a "disorderly" exit from the EU.
Ivan Rogers told friends that he fears a so-called hard Brexit would lead to "mutually assured destruction" for the UK and EU, The Sunday Times reported.
The newspaper quoted a "source familiar with the conversation" between Mr Rogers and Mr Cameron as claiming that Mr Rogers fears the UK is heading for a "car crash".
The source said: "Rogers spoke to Cameron. His biggest fear was that the biggest issue is not hard or soft Brexit, but whether we have an orderly or a disorderly Brexit.
"He thinks we are heading for a car crash, where we don't get a deal and we crash out with nothing".
However, Ms May said this morning that she is "ambitious for what we can get for the UK in terms of our relationship with the European Union because I also think that's going to be good for the European Union.
"Our thinking on this isn't muddled at all.

She added: "Yes, we have been taking time, I said we wouldn't trigger Article 50 immediately, some said we should, Jeremy Corbyn said we should, but actually there hadn't been any plans made for Brexit so it was important for us to take some time to actually look at the issues, look at the complexity of the issues, and that's why as I say we didn't trigger immediately but we will trigger by the end of March this year."
The prime minister insisted she will be able to secure control over immigration to the UK as well as favourable trading terms with the European Union during Brexit negotiations.
Mrs May used her first broadcast issue of the New Year to reiterate her belief that the trade versus immigration control issue is not "binary".
Ms May said: "Often people talk in terms as if somehow we are leaving the EU but we still want to kind of keep bits of membership of the EU.
"We are leaving. We are coming out. We are not going to be a member of the EU any longer.
"So the question is what is the right relationship for the UK to have with the European Union when we are outside.
"We will be able to have control of our borders, control of our laws.
"This is what people were voting for on June 23. But of course we still want the best possible deal for us, companies to be able to trade, UK companies to be able to trade in and operate within the European Union and also European companies to be able to trade with the UK and operate within the UK."
Meanwhile, Scotland's First Minister Nicola Sturgeon has hinted that a "hard" Brexit could see a second vote on Scottish independence within five years.
