Two years ago Jack McConnell launched Scotland's International Development Policy, promising to "change lives" in one of the world's poorest countries.

The magnificent Siberian tiger is on the verge of extinction. Poaching threatens to wipe them out as unscrupulous hunters kill the tigers to make illegal Chinese medicines. Now for the first time Frontline can reveal those medicines are on sale in Scotland.

In spite of it all, he says he has no regrets about falling in love with Angelika.

One of Britain's most notorious teenagers, Luke Mitchell, was sentenced to life for the brutal murder of his 14-year-old girlfriend Jodi Jones. He was portrayed as the personification of evil.

A decade ago the English law courts made a landmark ruling that was to have a huge impact on who should get funding for long-term care from the NHS. A court ruled that if your primary needs were health care then the NHS should pay for everything, whether you were in hospital or not. The guidelines in England were changed, but not in Scotland. Ross McWilliam investigates.
