London

The London Olympics will put Britain's capital in the spotlight, but some wonder how much of a payoff the Games bring in the long-term.

Fears are growing in London that the Olympics may not start smoothly. The union representing border agents at Heathrow airport is planning to go on strike a day before the ceremonies begin.

According to the Financial Times newspaper, four big European banks have joined Barclays in the not-so-prestigious club of financial institutions being investigated for rigging a benchmark lending rate called LIBOR.

The British government says it will have to deploy an extra 3,500 soldiers to protect the Olympic Games after a private security contractor abruptly said it would fall short.

Residents of some apartment buildings in London are upset that the British military plans to put anti-aircraft weapons on their roofs during the Olympic games.

While Wall Street had been bogged down by regulations and scandal, London took the crown for leading global financial center. Now, with the Barclays and LIBOR-rigging investigation, the British city could find itself being regulated as well.

The British Parliament has started investigating the ethics of London's financial center. This follows that big scandal involving the British bank Barclays, which was fined a half billion dollars for rigging a key interest rate called LIBOR.

Europe's tallest skyscraper is opening today on the south bank of the Thames River. It's called the Shard -- as in a shard of glass -- and it's more than a thousand feet tall. But the real challenge wasn't just building it; they also need to find a way to fill it up.

Tomorrow, The Shard will officially open in London. It's the tallest building in Europe at over a thousand feet high. Meanwhile, Britain's economy isn't looking so good.

The CEO of Barclays bank is out. Bob Diamond is leaving amid a scandal over banks colluding to fix the price of one of the most important interest rates in the world.
