Last year was a tough one to be a leader in the City. As regulators got tough on businesses in the finance, energy and infrastructure sectors, there was a moral panic about who pays how much tax, with various companies having their dirty washing put unceremoniously on display.

So you can forgive chairmen and chief executives for being unwilling to put themselves at the mercy of their critics on social media. But there are a brave few who have decided to take on the masses and, in the interests of transparency (or just because they have a lot to say), venture on to Twitter. Tweeting bosses: we salute you. Here are the 20 you need to follow in 2015.

*We've chosen to include Harriet Green, despite the fact she's stepped down as chief executive of Thomas Cook. This is partly because we're pretty sure that, having turned around Thomas Cook, she'll be back in a senior role in 2015 - and partly because her Instagram account is better than most of our friends'.
