As UK private equity engages with its critics, senior politicos have thrown their weight behind the industry.

The most high-profile intervention in recent weeks has come from none other than British prime minister Tony Blair, who has publicly praised private equity's positive effect on the country's economy.

Also supportive has been Ed Balls, a key ally of Prime Minister-in-waiting Gordon Brown and a potential future Chancellor of the Exchequer should the Labour Party remain in government after the next general election. In a recent interview with the Financial Times, Balls underlined that more disclosure would be welcome, but also stressed that private equity-driven innovation in the British economy was a good thing, and dismissed claims that the industry was “shorttermist” in its approach to running portfolio companies.

Balls' views on private equity contrast with those held by other senior figures in the Labour Party. Several of the candidates for Labour's upcoming deputy leadership election, including Peter Hain and Jon Cruddas, have called into question the tax treatment of private equity and its record on job creation. Some industry practitioners believe that this schism within Labour is the main reason why private equity has been so fiercely attacked by left wing politicians and trade unionists in recent weeks.

Meanwhile, over at Conservative Party headquarters, the Tories appear to be more uniform in their support of private equity. None of Britain's largest probusiness party's Members of Parliament have so far criticised the industry publicly. What's more, George Osborne, UK Shadow Chancellor, made it clear during a keynote speech at a BVCA dinner in March that private equity could count on him should his party make it into office.

To be fair, Osborne did qualify his support slightly by saying that private equity needed to be more transparent, take its social responsibilities more seriously and do more venture investing.

The latter appeal seemed a bit silly: UK private equity owes most of its success to the London-based buyout funds, and these funds won't even think about expanding into venture capital. But the BVCA grandees present at the dinner didn't seem to mind: judging by his remarks on the night, Osborne is fully signed up to the private equity cause – and as far as industry professionals pondering the future are concerned, surely that is all that matters.

UK investment trust Mithras has launched a new funds of funds business headed by Tandem Private Equity founder Gillian Brown. Mithras bought Tandem, itself a funds of funds business, in January. The establishment of Mithras Private Equity is the latest step in the investment trust's transformation.

UK mezzanine firm Intermediate Capital Group (ICG) has recruited Janine Peake as head of debt investor relations.

It is currently fundraising for ICG European Fund 2006, which held a first close in November last year on €650 million, and which has a target of €1.25 billion.

London-based Quester manages more than £200 million (€293 million; $387 million). It recently bought UniServity, a provider of web-based learning platforms, for £2.4 million.
