A spokeswoman emphasised that Uber was not closing its entire autonomous vehicle program, which will focus on limited testing in Pittsburgh, Pennsylvania, and two cities in California.

Uber aims to resume self-driving operations this summer, likely with smaller routes and fewer cars.

"We're committed to self-driving technology, and we look forward to returning to public roads in the near future," the spokeswoman said.

The FBI has admitted overestimating the number of seized mobile phones its investigators are unable to access.

It has seized between 1,000 and 2,000 mobile phones that remain locked, as part of its crime investigations, not the 7,800 it had previously claimed.

It said a computer glitch had led some devices to be counted several times.

The intelligence agency had previously complained Apple and other manufacturers' security measures were hampering its ability to investigate.

The news was first reported by the Washington Post, external.

Turkey's President Tayyip Erdogan says the country will take "different measures" to tackle double-digit inflation and a current account deficit after next month's elections.

Erdogan, speaking to former parliamentarians in Ankara, also appealed to Turks not to favour foreign currencies over the Turkish lira, which has lost around 20% against the dollar this year.

Currency volatility was not in line with the country's economic realities, he added.

It comes after Turkey's central was forced to raise a key interest rate to help support the lira. On Wednesday, the value of the currency sank more than 3%, before recovering.

Two US consumer rights groups have urged the Federal Trade Commission to investigate Tesla over its marketing of "Autopilot" assisted-driving software.

In a letter sent on Wednesday, the groups called the Autopilot name "deceptive and misleading".

A small number of drivers using the software have been involved in crashes.

Tesla says customer feedback shows "a very clear understanding of what Autopilot is, how to properly use it and what features it consists of".

Tesla instructs drivers to keep both hands on the wheel and eyes on the road while driving using Autopilot.

The 11 executives of Venezuela's Banesco bank - arrested earlier this month for allegedly "attacking" the country's rapidly-weakening currency - have been freed or are being released, chief prosecutor Tarek Saab says.

Four female executives have been freed, and their seven male counterparts were due to be freed on Wednesday, Saab told local television channel Globovision.

"With that, they are all free... but obviously our investigations are continuing," said Saab.

In early May, the government led by President Nicolas Maduro (above) said Banesco was being taken over for 90 days and its top executives jailed.

According to the minutes, policymakers once again debated the inflation path.

Several noted that recent wage data provided "little evidence" of overheating in the labour market, while some others saw a risk that "supply constraints would intensify upward wage and price pressures, or that financial imbalances could emerge".

Also, a number of policymakers said US trade policy raised a "particularly wide" range of risks for economic activity and inflation, and some said the uncertainty could hurt business spending.

Most Federal Reserve policymakers thought it likely another interest rate increase would be warranted "soon" if the US economic outlook remains intact, minutes of the central bank's last policy meeting show.

At the 1-2 May meeting Fed policymakers unanimously decided, as expected, to keep the benchmark rate unchanged.

But Wednesday's just-released minutes say: "Most participants judged that if incoming information broadly confirmed their current economic outlook, it would likely soon be appropriate... to take another step in removing policy accommodation."

The Turkish central bank has hiked one of its key interest rates 300 basis points (bps) to bolster the lira after the currency plunged to historic lows against the US dollar.

The bank said after an emergency meeting of its monetary policy committee it was raising one of its lending rates from 13.5% to 16.5%.

Earlier, the lira lost over 3.5% in value against the dollar but sharply gained in value after the bank's announcement, gaining 2.1%.

Gemma writes: "Like a lot of the British public I love M&S but at 30 years old, I am one of the few in my friendship group that would shop there for clothes as well as food.

"Focus on the stores in high performing areas and improve the shopping experience. I work near the Fenchurch St store (City of London) and it has got so dated.

"I grew up near the Sprucefield Store (Northern Ireland) and the two could not be more polar opposites. The Sprucefield store opened a lovely high-end deli counter/cafe were you could sip on a glass of bubbles and order some delicious plates - more stores need this! Make the experience feel so much more special.

"Their online experience; especially the app, is not easy enough to navigate around. They really need to look at their competitors here such as ASOS and make it easier to shop "New In", "Dresses" "Shoes" etc.

"My friends and I love the Rosie for Autograph brand but they probably do need a curvaceous ambassador also.

"Food: Don't steer away for high-end quality produce, but focus more on the meal deals and more deals on wines. Waitrose is your biggest competitor in this space so you need to attract these customers with better range off high quality products."
