Shortly after Philip Clarke made his surprising – and, it turns out, prescient –admission at a conference in March that his days as Tesco chief executive were probably numbered, the boss of another blue-chip British company asked me, worriedly: “Does it sometimes take two CEOs to turn a company round?”

There is no longer much call for poetry at Microsoft’s devices division, the bulk of which consists of Nokia’s old handset business.

Stephen Elop, former Nokia chief executive, now heads the Microsoft unit and on Thursday had the task of announcing 12,500 job cuts (out of 18,000 in total). The axe will fall on many former Nokians who remember the flights of fancy in Mr Elop’s 2011 “burning platform” memo, in which he urged them to make a leap into the unknown to help turn the company around: Read more

Madeleine Albright, former US secretary of state, famously said there was “a special place in hell” for women who don’t help other women. But new research suggests that women leaders – and managers from ethnic minorities – will also be damned if they go out of their way to advance people who look like them.

A paper to be presented at next month’s Academy of Management annual meeting says women and non-white leaders who value diversity – and show it through their actions – are “systematically penalised with lower performance ratings” by their bosses. By contrast, valuing diversity earns white men higher ratings for both warmth and performance. The net effect, however, is that the “glass ceiling” is reinforced. Read more

When the lucrative business of advising on mergers and acquisitions was in the doldrums, consultants spread the idea that crisis management was “the new M&A”. They wielded news stories such as BP’s Gulf of Mexico oil spill, Rolls-Royce’s disintegrating Qantas engine, and Toyota’s jammed accelerator pedals to frighten clients into contracts aimed at helping them cope with such disasters.

The FCA: not to blame for social media caution (Chris Ratcliffe/Bloomberg)

Some British banks have a long way to go with social media. At a conference on Wednesday morning, one institution admitted its tweets were vetted by no fewer than eight different departments before they were sent.

The financial sector’s attitude to social media regulation seems to be a mix of fear and loathing. On a show of hands, only a couple of delegates at the Social Media Leadership Forum, where I was a speaker, revealed they were not scared about using social media, even though most believe it is a great opportunity. In part, this is because companies are waiting for guidance from the Financial Conduct Authority, first promised for early 2014, that the FCA says is now due later this summer. Even after this extended wait, the proposals will be subject to consultation before they are finalised. Meanwhile, other sectors’ social media strategies are evolving at web-speed. Read more

While waiting in a big Manhattan hospital about 15 years ago, I glimpsed the chairman of one of the world’s biggest banks in a consulting room. I never found out why he was there. If he was ill, his employer never said and the man is now enjoying a long and apparently healthy retirement.

Pale, male and stale: what's next for the boardroom?

As boards gradually move towards better balance by gender, what is the next frontier?

Alan Mak, a 30-year-old non-executive director of Havas Worldwide (UK), thinks boards should make it a priority to take on more young directors. He and I have gone head-to-head on the issue in print and we took the debate onto Twitter on Thursday to test the mood. Read more

What puzzles me about Sports Direct’s campaign to pay founder Mike Ashley a bonus – which finally succeeded on Wednesday, despite shareholder opposition – is that it focuses City attention on the weak spots in the sports retailer’s make-up: its governance and its dependence on Mr Ashley himself. Read more
