Often when Amazon parks its tanks in a new market, investors sell off shares in its soon-to-be rivals. It happened to Ocado when Amazon announced it would deliver groceries in the UK. 

Now it's happening to TrueCar - a US price comparison website for used cars. Shares are down nearly 10% since Amazon launched its car review website.

The drop is a direct reaction to Amazon Vehicles, according to RBC Capital Markets analyst Mark Mahaney. However, he notes the Amazon site is unlikely to materially affect TrueCar's business anytime soon.

But what's got tennis fans particularly excited is that Federer will team up with Rafael Nadal. Two of the greatest rivals in the game (with Nadal holding a 23-11 advantage), the Swiss and the Spaniard are set to play doubles together in the inaugural Laver Cup. 

London couriers for UberEats, the food delivery service launched by the taxi-hailing app company, are pushing ahead with a protest on Friday. They plan to demonstrate outside Uber's office for the London living wage of £9.40 an hour.

Amazon explains that its new car review website is an extension of the Amazon Automative store and Amazon Garage features on the US website. 

More than 35 million people have uploaded details about their car to Amazon Garage, which enables users to view and find parts for their specific vehicle.

Explaining the company's latest land grab, Adam Goetsch, director of automotive at Amazon.com, said: “Our goal is to support customers during one of the most important, research-intensive purchases in their lives by helping them make informed decisions every step of the way."

Amazon famously started in Jeff Bezos' garage. More than 20 years later, the world's biggest online retailer is turning again to garages, but this time to the cars that its millions of users own. 

The company has launched a car review site called Amazon Vehicles, offering research, reviews and other information on new and used cars on its US website. 

It won't sell cars. But it does have car specifications, images, videos and customer reviews, as well as enabling customers to ask each other questions about cars. 

The reviews also fit in with its Amazon Automotive store which sells car parts and accessories.

Collapsed department store BHS is now into its final few days. Some shops may still be trading come Sunday, but in most cases the closing down sales will be coming to an end and the doors shutting for the final time.

Shopworker union Usdaw said "this weekend marks the end of an era, but the saga at BHS continues". The trade union called on Sir Philip Green to offer jobs to BHS staff elsewhere in his Arcadia retail empire and to "sort out" the BHS pension scheme.

Peppa Pig owner Entertainment One finished as the biggest faller on London's FTSE 250 after ITV called off its £1bn takeover bid.

Shares fell more than 14% to 215.10p - well below the 236p a share ITV had been willing to pay. 

"ITV just wasn’t prepared to fatten up its bid for Entertainment One," said ETX Capital's Neil Wilson. EOne's investors may be hoping for another suitor, but any bidders will likely need to pay a hefty premium, he said.

Frosty weather in spring and a summer heatwave is likely to result in French wine production being down 10% this year, officials say.

In the Champagne region, the harvest is expected to be down by about a third. Prices will rise, although one French wine trader said the Brexit effect would be a greater inflationary pressure for UK buyers.

Lord Tim Bell - a former spin chief for Margaret Thatcher - has stepped down as chairman of PR firm Bell Pottinger. 

Lord Bell, who has called himself an unreconstituted Thatcherite and advised controversial figures such as former Chilean dictator General Pinochet, has stepped down from the business he started nearly 30 years ago with immediate effect.  

"Lord Bell has decided he would like to step back from the day-to-day running of the business, but not to retire and from next year he will continue to provide his personal advice to clients through a new business, which he will be forming," Bell Pottinger said.

Speaking of the Epipen row in the US, the embattled manufacturer Mylan has come under renewed pressure from Democratic presidential candidate Hillary Clinton.

She criticised a move by Mylan earlier today to expand discount programmes, external for its Epipen allergy treatment. The discounts were welcome but "insufficient", because it won't lower the overall price of the Epipens, Clinton's spokesperson said. 

It's been reported the price of a two-dose package increased to $600 from about $100 nine years ago.

The FTSE 100 finished 19 points lower at 6,816.90 points, with healthcare firms among the biggest fallers. Hikma Pharmaceuticals took the heaviest hit on the blue chip index, falling 3.8%, while drug maker Shire fell 2.5%.

The roots of the sell-off are on the other side of the Atlantic, where a controversy about price hikes on Epipens has hit US pharmaceutical shares.  

"European healthcare stocks have been caught in the storm of a US biotech sell-off," said Jasper Lawler of CMC Markets. "Another attack on price gauging in the industry from presidential hopeful Hillary Clinton puts pricing power in the industry at risk."
