So where in the world can you find the highest rates of drug-resistant tuberculosis? I'll give you a clue - it also happens to be one of only two regions in the world where the number of new HIV cases continues to rise every year. It's not Africa. It's not South America or even Asia. It's the European region.

No one denies that TB in cattle is a serious problem. It results in the premature slaughter of many thousands of cattle each year, with devastating impacts for farmers, and at a huge cost to the taxpayer in testing, inspection and compensation. But killing badgers isn't going to reduce TB in cattle.

We need to take the proof that aid works out to our communities, and we need to show our politicians and media the full story when it comes to aid and development. We need to argue that aid can work wonders - when it's spent well.

Nobody wants to cull badgers. But equally no country in the world where wildlife carries TB has been able to eradicate the disease in cattle without tackling it in wildlife too.
