That's all on another busy day of Brexit developments. Join us from 6am tomorrow for more on this, and other news from the world of business and finance.

Night, night  

Wall Street enjoyed a third straight day of gains as Britain's central bank raised the prospect of stimulus and consumer stocks gained on news of Mondelez International's $23bn bid for Hershey. 

The Dow Jones ended up 235.31 points, or 1.33%, at 17,929.99, and the S&P 500 gained 28.09 points, or 1.36%, to 2,098.86. The Nasdaq added 63.43 points, or 1.33%, to 4,842.67. 

All ten S&P sectors ended higher, led by a 2.2% climb for consumer staples shares.

US markets fell sharply last week after the UK voted to leave the European Union.

The BBC's Zoe Thomas has been to the Atlanta HQ of the world's largest delivery company, UPS. Chief executive David Abney tells her that the Brexit vote seems to have brought more "emotion" than "change".

The firm is used to trading across different jurisdictions and under different trading rules. 

He says: "We're not going to change our investment plans whether it be in Europe or in the UK. So we feel very comfortable that our customers are still going to have some very complex supply chain needs and our strategies and investments are going to continue to take place.”

Safety regulators in the US have called for the urgent repair of more than 300,000 aging Honda vehicles fitted with Takata air bags.

Japan's Takata and the car companies that use its air bags have faced huge problems over the risk of the inflators rupturing in a crash.

The National Highway Traffic Safety Administration cited new test data that shows some Honda models from 2001-2003 have as high as a 50% chance of an air bag rupture.

Takata air bag inflators have been linked to as many as 14 deaths worldwide, including 13 in Honda vehicles, because they can deploy with too much force and send deadly metal fragments flying.

The European Union's top trade official says the UK cannot begin negotiating terms for doing business with the bloc until after it has left.

"First you exit then you negotiate," Cecilia Malmstrom told BBC Newsnight.

After Brexit, the UK would become a "third country" in EU terms, she said - meaning trade would be carried out based on World Trade Organisation rules until a new deal was complete.

A recent trade deal with Canada took seven years to negotiate.

The Canadian agreement will also require ratification by all EU countries, adding another one to two years before it takes effect.  Read more here

Confectionery giant Hershey has rejected a $23bn (£17.3bn) takeover bid by Mondelez International.

Mondelez - which owns Cadbury's and Kraft and makes Oreos cookies  -  wants to expand its presence in the US and create the world's biggest confectionery company. 

 "The board of directors of the company unanimously rejected the indication of interest and determined that it provided no basis for further discussion between Mondelez and the company," Hershey said in a statement. , external

By taking over Hershey Mondelez would gain control of the production and distribution of its Cadbury brand chocolates in the US, which Hershey currently holds the licence to produce, paying royalties to Mondelez.

It would also mean Mondelez had the rights to produce and distribute Kit Kat in the US.

Hershey's shares jumped 15% following the bid.

With just an hour of trading to go on Wall Street - what's the picture over there?

Well, the major indexes are all still up ... buoyed by that speech earlier by Bank of England Governor Mark Carney hinting at an interest rate cut and/or further quantitative easing. 

A short while ago the Dow Jones  stood at 17,898.42 - a rise of 1.15%.

The Nasdaq was up 1.06% at 4,829.86.

And the S&P 500 was at 2,094.56 - up 1.15%.  

The price of Brent crude oil fell by more than 2% today - pushed down by in part by the prospect of Nigeria and Canada pumping more oil. 

Nigerian oil production has risen following pipeline repairs and the fact that there haven't been any new big militant attacks in the Delta region, the state oil company said earlier this week.  

The news helped Opec's oil production climb in June, as did increased supply from Iran and the Gulf. 

And the supply disruptions caused by the Canadian wildfires are expected to be virtually over by September.

Ratings agency Standard and Poor's has cut its credit rating for the European Union following last week's Brexit vote. 

S&P Global Ratings said it was cutting its long-term rating on the EU from AA+ to AA because the UK's leave vote meant "greater uncertainty" over the EU's revenue forecasting, long-term capital planning and adjustment to key financial buffers. 

S&P said it had to review its "previously favourable opinion of solidarity within the EU" from positive to neutral because its previous view was based on all 28 member states remaining inside the European Union. 

Will the UK financial technology sector be poached by a European rival? Lawrence Wintermeyer, head of industry body Innovate Finance, gives the BBC's Manuela Saragosa his view.

So now we know - Boris Johnson won't stand in the Conservative Party leadership contest.

However, five other candidates had come forward by today's midday deadline.

Throwing their hats into the ring are Justice Secretary Michael Gove, Energy Minister Andrea Leadsom and ex-defence secretary Liam Fox - all of whom backed the Leave campaign in the run up to the EU referendum.

Home Secretary Theresa May and Work and Pensions Secretary Stephen Crabb - both of whom supported the Remain camp - are also standing.

But whether the candidates were pro- or anti-leaving the EU, the employers' organisation, the CBI, has the same message for all of them.

Let's quickly return to that interview that Jes Staley, chief executive of Barclays gave to the BBC earlier. 

Here you can listen to what he said about how Brexit would affect the bank's jobs in London.

The post-Brexit  debate rumbles on ...

Here are some interesting thoughts about what happens now from Chatham House - the Royal Institute of International Affairs.
