Greek prime minister Alexis Tsipras (pictured) has insisted that his finance minister Yanis Varoufakis, under fire from his European peers over the bailout talks, continued to enjoy the government's support. He will continue to lead the negotiations, but Euclid Tsakalotos, minister of international financial relations and part of the foreign ministry, will handle the coordination within Varoufakis' negotiating team.

Another reason BP is probably not a potential takeover target is concerns over future litigation about the Deepwater Horizon oil disaster, Michael Hewson from CMC Markets tells BBC World News. "They've already set aside $43bn - $45bn with respect to that, and that's going to be ongoing." Also, there are regulatory concerns, he adds.

As well as announcing that Whitbread chief Andy Harrison plans to leave, the food and hotels group also posted annual results, external. Underlying pre-tax profit rose 18.5% to £488.1m on revenue up 13.7% to £2.6bn. Profit at its Costa Coffee division rose 20.7% to £132.5m.

BP said that "oil and gas prices in the quarter were sharply lower than a year earlier". It said that the average Brent crude price of $54 per barrel, which was half that of the same period in 2014, was the lowest average price since the first quarter of 2009.

Oil giant BP's first quarter profits have fallen to $2.6bn (£1.6bn) from $3.2bn a year earlier. Bob Dudley, BP group chief executive, said the results reflect a "weaker environment" in terms of oil prices.

Whitbread says Andy Harrison has decided to retire as chief executive. He intends to go by February 2016, "ensuring a smooth transition", the company says. A succession process, led by the chairman Richard Baker, is considering external and internal candidates.

An on-air confession from regular BBC guest Holly Cook, from investment website Morningstar. She tells Today that she has a "huge crush" on Yanis Varoufakis, the Greek finance minister. She admires his strong philosophy, but that is a reason for the stalemate in negotiations with EU-IMF creditors. He needs to be realistic, not idealistic, she says.

Is BP a takeover target? Michael Hewson, senior analyst at CMC markets, tells BBC World News: "Speculation is rife that it could be." But he doesn't think that it could be. "It's current market capitalisation value is £87bn... that's what the company's worth right now. Any prospective suitor would have to bid above that. Massively deep pockets."

Although the markets responded favourably to reports of Greek finance minister Yanis Varoufakis being sidelined in Greek debt negotiation talks, the situation hasn't changed that much, Holly Cook from Morningstar tells Wake Up to Money. "This re-jig of people involved in the negotiations over the Greek debt - no matter who is actually doing the talking, they can't stray too far from what their original mantra was, because their original mantra was all about anti-austerity... They've got a relatively tight margin for manoeuvre," she says.

The Greek Prime Minister Alexis Tsipras has delivered a robust defence of his government's policies. Speaking in a lengthy late-night television interview, Mr Tsipras said he believed a deal could be reached soon with the country's international creditors. That follows a shake-up of his team negotiating with EU and IMF creditors, and the sidelining of outspoken finance minister Yanis Varoufakis.

Apple continues to do better than expected, based on "soaring iPhone sales and very strong numbers in China", Cary Leahey of Decision Economics tells Wake Up to Money. "They're able to increase market share at the same time they're raising prices. Quite a formidable achievement," he says. But not all is rosy for Apple. "The iPad sales are sluggish, they're being hurt at both ends by not only ever-thinner laptops, but also the fact that smartphones are getting bigger and bigger, and cutting into their business."

BP is likely to report "significantly lower operating profits" this quarter, David Hunter from Schnieder Electric tells Wake Up to Money. "That really reflects, in the main, the reduction in the global oil price." On BP being a possible takeover target, Mr Hunter says: "It's natural, that BP, with the problems that it has gone through in the last five years since the Gulf of Mexico spill, is talked about in those terms. [Though] it is still a very big company, well over $130bn market capitalisation in size."
