In this week’s show, your emails on the David Sterling affair and we examine mega corporate takeovers – especially Pfizer’s current bid for giant UK pharma firm, AstraZeneca. We ask: should businesses which are national goods be nationalised? And we return to Ukraine : are there Russian boots on the ground? Then, Monica Lewinsky, threatening builders, and the big issue: can you test people for consumption of cheese? Listen in and tell us what you think at tro@gadgetdetective.com
