The pharmacies in Sainsbury's supermarkets could soon wear the Lloyds logo (the chemist that is, not the bank) after the competition watchdog approved a takeover by Lloyds' German parent company, Celesio.

But the Competition and Markets Authority said Lloyds would have to sell 12 of its pharmacies before the deal can go ahead.

While Barclays boss Jess Staley did not make the blunt Brexit warning made on Thursday by his opposite number at Lloyds Banking Group, Antonio Horta-Orsorio, the fine print of the Barclays statement makes plain its concerns.

It says the referendum result means “the long-term nature of the UK's relationship with the EU is unclear … in the interim, there is a risk of uncertainty for both the UK and the EU, which could adversely affect the economy of the UK and the other economies in which we operate”.

Barclays also lays out the detailed risks to its UK business, including the threat to “passporting” rights, which allow banks and other financial services companies to sell their services across the EU, and the threat to hiring staff from the possible end to the free movement of people.

The FTSE 100 is down a touch as trading gets underway at 6,705 points.

"Sources have told me that Chinese officials – here to sign up to their stake-holding in Hinkley – will now be returning home," says John.

But he adds: "There’s no suggestion that the new government is going cold on this long-delayed project."

Uncertainty surrounding the EU referendum has led to a slowdown at estate agents Foxtons, external.

The firm says it "experienced a sharp contraction" in the second quarter of the year, and that "the overall level of property sales transactions made in London during the first half of the year is substantially down on last year". 

Things aren't looking good in the near future either. 

"The result of the referendum to leave Europe is likely to lead to a prolonged period of further uncertainty and we do not expect London residential property sales markets to show signs of recovery before the end of the year."

Shares in Foxtons have fallen by 25% since the result of the Brexit vote was announced.

This stunning new development came all the way from the top of government and the timing seemed calculated to cause maximum impact.

EDF executives were taken completely off guard, the post-Brexit run of major investment is abruptly halted and what precious entente cordiale in Anglo-French relations there is left after the EU referendum result seems diminished.

EDF said it remained confident about the government's commitment to build nuclear reactors in Hinkley Point despite Business and Energy Secretary Greg Clark saying that a final decision will be made in the early autumn. 

EDF chief executive Jean-Bernard Levy said: "There is no comment to make. The statement made by Mr Clark is perfectly clear. I have no doubt about the support of the British government led by Mrs May."

Asked on an analyst call for EDF's results about the possible impact on the project's construction schedule, Mr Levy said that the timing for Hinkley Point is under permanent review, depending on events - notably the effective date of signature of the contracts. 

Core profits at Barclays (that's the bit of the business that you've heard of, pretty much), are up 19% at £4bn. 

It's the so-called "non-core" part, which includes lots of divisions Barclays has already agreed to sell, that is dragging the group profits down. Its losses ballooned by 155% to £1.9bn.

IAG chief executive Willie Walsh tells Today that a weaker pound hits the airline owner because it reports in euros, whereas British Airways makes its money in sterling. The company also pays for fuel in US dollars.

He "firmly believe that business will settle down" in the wake of Brexit vote. "People will continue to fly", so in the long term it won't have a material impact on the business, Mr Walsh says.

Everyone is fed up about the delay on making a decision about Heathrow expansion, he adds, and it is unfair on people living near the airport. 

Speaking of electricity and the like, Scotland business editor Douglas Fraser points out that Ofgem has announced a probe into SSE, external today.

IAG's operating profit before exceptional items for the half year was €710m, compared with €555m last year. Excluding Aer Lingus the figure was €668m. 

That's despite a negative currency impact of €148m in the second quarter due to the weaker pound.

"Taken together, the picture in the second quarter is one of strong and accelerating progress against our strategy," says Barclays boss Jes Staley.

"We remain confident that it is the right plan for Barclays, and see no reason to adjust it, or the pace of delivery, in light of the vote by the UK last month to exit the EU."  

IAG, the owner of British Airways, Aer Lingus and Iberia, says it has "continued to experience a weaker trading environment" in the UK, which represents about a third of total revenue. "On top of this, continued pound sterling weakness would reduce pound sterling profits when translated into euros in what is traditionally the most profitable part of the year," the company said.

Willie Walsh, IAG chief executive, said: "We're reporting another strong performance in quarter two with an operating profit of €555m before exceptional items, which is up from €530m compared to last year. Excluding Aer Lingus it would be €487m."

Barclays reports a 21% drop in pre-tax profits to £2bn.
