The United Kingdom is now in a so called transition period until the end of the year as the long term future relationship with the EU is negotiated.

Today.

The prime minister made his first major speech on Brexit since the general election, and at the same time, Michelle Barnier, the lead negotiator of the U, outlined his position.

Is our political editor Laura Kuhns, Big explains.

Boris Johnson insisted there was no need to follow EU rules, but critics say that his plans are unrealistic.

This site stood watch over our fortunes for more than 300 years, times the 18th century, captured flamboyantly on the ceiling of the Royal Naval College by the Thames.

This is it.

This is the newly forged United Kingdom looking down on the prime minister, hoping for his own glory.

We've made a choice.

We want a comprehensive free trade agreement similar to Canada's, but in the unlikely event that we do not succeed, that our trade will have to be based on our existing withdrawal agreement with the U.

That could mean taxes on imports and customs checks.

More autonomy for the UK, though and a clear no to being bound by EU rules.

I dispel the absurd caricature of Britain as a nation bent on the slash and burn of workers rights.

Andi.

Environmental protection as if we're saved from Dickensian squalor only by enlightened you regulation it was only thanks to Brussels.

We're not preparing to send Children back up chimneys on arrival platform on the other side of the channel.

We are ready to offer the Islay Abby should trade deal.

The more we have common standards, the higher quality access do you will be able to offer to its markets.

But this will be up to the UK to decide.

In other words, they use message to Boris Johnson.

The more you want to tak away, the harder it will be to do business.

If it is a choice between no comprehensive deal or sticking to you rules, you've suggested you would rather have no comprehensive deal.

But do you accept that that might have significant costs for jobs, businesses and people's prosperity's, as well as the benefits that you claim there might be when I hear prophecies of doom?

I problem.

I've heard them before.

I don't believe in them is a fantastically robust, dynamic economy and will continue to be so.

It will be not easy, but obviously it's good for everybody.

If there is a good deal at the end and he's got the team to put it together, I'm optimistic can do it.

This is about how we do business with the EU and the rest of the world in years to come.

The prime minister believes for Brexit to be worth it, we have to be able to do things differently.

But the U reckons for access to their markets.

We ought to stick closely to their rules, and that's the Clash.

But in truth, this is the beginning of what will be 11 months of hard bargaining.

And as you might expect that this stage, there's an awful lot of chest beating going on.

The prime minister didn't even want to mention the word Brexit today, but you can't avoid the fact just a few days on this, plenty of argument over our place in the world that's yet to come.

Lorcan Spark, BBC News with me is our economics editor, Faisal Islam.

Let's talk about trade, Faisal, where we right now So we've left.

But just how far we depart depends on this negotiation.

Right now, the UK you regulations are perfectly aligned.

But broadly speaking, as they diverge, we have mawr of a room to change our rules, regulations, trade deals.

But also the flip side of that is that it makes more complicated our current seamless trade with the EU.

So that's the sort of parameter of the choice when people talk about a Canada style deal.

How realistic is that on What did they mean by it?

What you mean by that is the sort of deal the U has with Canada, which has checks on regulations at the border but in broad terms means that you do away with taxes on trade tariffs for goods on has a week set of common standards a level playing field.

Now that's what the UK thought it negotiated in the renegotiation of boys Johnson.

What you said today is that what goes for Canada can't go for the UK It's too close to big a shared economy on that it would have to have a very strong sets off level playing field, particularly on supports for industry and for those people who talk about, you know, the supposed the ideal of on Australian model.

What do you make of that?

Sounds very sunny doesn't actually exist because there is no deal between Australia on the you.

And that means serious tariffs on serious industries car industry, food industry that would have an impact.

This is a method through which the government can sugar coach the idea of there being no trade deal, something they pretty much said wouldn't happen but is possible if we reject the idea of alignments for a Canada style deal.

Faisal, once again, that's very much positivism that I can't be said it.
