He told the BBC's Andrew Marr the UK would not diverge from current EU trade regulations "for the sake of it".

Mr Barclay added the government's objectives for the trade talks would be published after Brexit on 31 January.

Prime Minister Boris Johnson will make a speech next month setting out more details, he said.

Mr Barclay's comments come after the US treasury secretary said his country wants to agree to a post-Brexit trade deal with the UK this year.

After Brexit happens at 23:00 GMT on Friday, the UK will be free to negotiate and sign new trade deals with countries with no existing EU deals - like the US.

The UK then enters into an agreed transition period with the EU, which lasts until 31 December 2020. During this time the UK will aim to negotiate a free trade deal with the EU to ensure that UK goods are not subject to tariffs and other trade barriers.

Speaking to the BBC's Andrew Marr, Mr Barclay said: "We are going to publish our objectives for the negotiation and we will set that out in due course after the 31st.

"The key issue is that we will have control of our rules, we will not be a rule-taker, we will not diverge for the sake of diverging.

"We start from a position of alignment but the key opportunity is that we will be able to set our standards, high standards, on worker's rights, on the environment, on state aid as part of that trade policy."

He said "both sides are committed" to securing a trade deal by the end of December, adding: "It's in both side's interests to keep the flow of goods going."

'Simpler immigration rules'

Irish minister for European affairs, Helen McEntee, told Sophy Ridge on Sky News that "Brexit is really only at half-time, we have a huge amount of work still to do".

"However, the idea that we can negotiate a trade deal with one that is comprehensive, one that provides very little change for our citizens, not just in the UK and Ireland, but the EU as well, within about a 12-month space, it's very difficult."

The new European Commission president Ursula von der Leyen has previously shared concerns about the timeframe, saying it would be "impossible" to reach a comprehensive trade deal by the end of 2020.

Meanwhile, the home secretary told Sophy Ridge UK businesses have been "too reliant on low-skilled cheap labour from the EU".

Priti Patel said the government will be able to control levels of low-skilled migration after Brexit.

She also confirmed that the Migration Advisory Committee will report this week on the UK's future immigration system.

The government was "absolutely determined to change the immigration system, end the complexity of the immigration system, have simpler rules, have a points-based system where we can absolutely have people that bring the right kind of skills for our labour market", she said.

On the UK's post-Brexit relationship with EU rules, Ms Patel appeared to adopt a harder approach than Mr Barclay, saying: "In terms of divergence, we are not having alignment. We will be diverging. We want to take control of our laws, money and our borders."

Last week, Chancellor Sajid Javid said the UK would use the power to diverge from EU rules on trade only when it was in the interests of business.
