One of France's presidential hopefuls has said that Britain must face the consequences for voting to leave the European Union.

Emmanuel Macron said: "If your government decides to organise a Brexit, I will be pretty tough on it."

Mr Macron told Channel 4 News: "We have to preserve the rest of the European Union and not to convey the message that you can decide to leave without any consequence." 

He said there was no desire to "punish" the UK but "it cannot be a game where Britain can maximise their interests without taking into consideration the EU's interests".

Shares in Apple are currently trading at a record high thanks to a note by investment bank Goldman Sachs which reckons the company's services business is undervalued.

Its stock rose by 1% to $133.46. 

Apple is focusing on growing its services side of its business to counter any slowdown in its hardware sales.

While services revenue is comparatively small compared to, for example, the iPhone - $24.3bn compared to $136.7bn in the most recent full financial year - it is gaining momentum. 

Service turnover rose from $19.9bn in the previous year compared to sales of iPhones, iPads and Mac which all fell in the year to 24 September 2016.

The US Senate is set to confirm veteran banker Steven Mnuchin as Treasury Secretary later today.

Then, of course, he's got to get on with appointing his team.

CNBC is reporting, external that several Wall Street veterans are likely to join him, including Jim Donovan who could come over from Goldman Sachs to become deputy treasury secretary. They also put Justin Muzinich, a former Morgan Stanley banker in the frame, possibly as undersecretary for domestic finance. 

The White House team of course already includes former Goldman Sachs alumni Gary Cohn as national economic council director, and advisers Dina Powell and Stephen Bannon.  

Republicans will argue their experience is what qualifies them for the job. Democrats think its all a bit too cosy.

Trump is questioned on NAFTA, and is reminded that while he has spoken a lot about Mexico he has said little on Canada.

Trump and Trudeau say they have also been discussing the role of women in the workplace and have created the Council for the Advancement of Women Entrepreneurs.

"We must work to address the barriers faced by women and women entrepreneurs."

The Greek debt crisis rumbles on.

It has been widely reported that Greece, the International Monetary Fund (IMF), and the country's eurozone lenders cannot agree on letting the country have more funds as part of its previously agreed bailout. 

But the IMF managing director, Christine Lagarde, has told Reuters that it is doing its best to agree on bailout loans for Greece, but cannot compromise its principles and cut a sweetheart deal for the country. 

She added that, in her view, a cut in Greece's debts could take place without international lenders having to take write-downs on their loans - an issue of great concern to European Union creditors.  

A BBC investigation has found that Tesco customers are being short-changed by promotions which have expired but are still advertised on the shelves.

More on the Co-op bank putting itself up for sale.

Chief executive Liam Coleman has told BBC News that the bank is hoping for a sympathetic buyer.

He says: "Any person that is considering, I think, what is the key strength of this bank will understand that the values and ethics plays a vital role in terms of the relationship that our customers have with us," he said.

"They tell us, in the research that we do, that it's extremely important to their relationship with us. 

"And I'm sure that anybody looking at the bank from the outside will come to very much the same conclusion," he added.

Ahh, Valentine's Day, it really is a marketeer's dream.

Here at New Broadcasting House we've been receiving some absolute corkers.

It turns out that America is the most romantic nation based on trips to florists, followed by France leaving Britain limping behind in third place. 

Read into that what you will.

Second time lucky for Glencore which has just acquired a 31% stake in the Mutanda mine in the Democratic Republic of Congo.

Glencore is buying the shares from Dan Gertler's Fleurette Group. 

It is also acquiring a 10.25% holding in the Katanga mine from the colourful Israeli mining entrepreneur. That mine is also in the DRC, one of the poorest countries in the world. 

Mr Gertler has been criticised in the past over his business deals in the DRC amid claims he was able to buy mining assets at low prices because of his friendship with Joseph Kabila who has been the country's president since 2001. Mr Gertler and Fleurette have denied the claims. 

Glencore originally attempted to buy the 31% stake in the Mutanda mine in 2015. Today's deal will give it total control of the mine. Both deals are worth a total $960m.
