He brags that he would have won the election, smashes foreign-policy porcelain and, above all, demonstrates childish vindictiveness - the departure of the outgoing US president Obama.

Barack Obama has announced that the USA will retaliate against Russia for its interference in America's presidential election. But Obama's threats have always been laughable.

As a result of his time in office, Barack Obama, hailed as a messiah after his election victory eight years ago, has now handed the presidency of the USA to Donald Trump.

As an absolutely impartial observer - I'm neither a fan of Trump nor Clinton - my judgement on the second televised debate couldn't be clearer: Trump's appearance was a disaster and will only accelerate his slump in the polls.

"I feel great, I feel great", was how Hillary Clinton lied about her pneumonia, moments after coming dangerously close to collapsing. And the smile on her face as she did so was as artificial as ever.

Germany's media are unanimous in warning against Donald Trump, but that's not enough of a reason for me to be against him.

Property prices are spiralling upwards. Is it still sensible, against such a backdrop, to buy? An investor friend of mine recently told me that he has just sold an apartment building in Berlin for 50% more than he had paid for it, at a price-to-rent ratio of 37. And this wasn't a luxury property he was talking about, neither was it in excellent condition or in a prime location, it was nothing more than a decidedly average, 1970s apartment building.
