Michael Spencer

Michael Alan Spencer (born 30 May 1955, Kuala Lumpur, Malaysia) is a British businessman; the chief executive of ICAP, the FTSE-100 listed world's largest interdealer broker. He is also currently the owner of spread betting firm City Index.

In the Sunday Times Rich List 2008 ranking of the wealthiest people in the UK he was placed 62nd with an estimated fortune of £1,150 million.

Spencer masterminded a dramatic increase in funding from financiers to the Tories ahead of the 2010 general election.

Conservative Party donor and persuasive City fundraiser

Spencer was Conservative Party treasurer from 2005 until he stepped down in October 2010. He reportedly 'masterminded an aggressive charm offensive' which saw funding from the financial services sector soar, jumping from £2.7m in 2005 to £11.4m in 2010. The City now accounts for more than half the Tories' funding - 50.8 per cent in 2010.

The party's biggest financial services donor was private investment company IPGL - of which Spencer is the majority shareholder, along with his wife and family trusts. It gave £806,864 to the Tories during Spencer's stint as treasurer. IPGL owns 18 per cent of Icap. Another Spencer offshoot, Intercapital Private Group, donated £365,000, while BSN Capital Partners, a hedge fund that is an associate company of Icap, gave the Tories £170,000.

Exerting pressure for lower taxes

Cuts to corporation tax and the 50p rate

In November 2009 Spencer was quoted in an interview with the Financial Times that he was "hopeful" of even deeper cuts in corporation tax than George Osborne had already signalled, from 28 per cent to 25 per cent. "I am hopeful that, over the next parliament . . . we will get corporation tax down towards the 20 per cent level."

Spencer told the FT he was speaking in a personal rather than an official party capacity. The FT however pointed out that "his call for a further 5 per cent cut - costing an estimated £4.8bn, without allowing for any offsetting increase in economic activity - chimes with signals sent by the Tory leadership".

So far, his hopes have been partially met. In March 2011 the new Coalition government's Budget brought a 'surprise cut' in corporation tax by two percentage points to 26pc from April 2011 (double the previously proposed cut), along with the announcement that by 2014, corporation tax will be reduced to 23pc (instead of decreasing to 24pc over four years).

Spencer has also consistently spoken out strongly against the 50p tax rate brought in by the previous Labour government. In the same interview he said: "I believe and I hope and I expect that that will be reversed in the foreseeable future."

Fury at the EU's Financial Transactions Tax

More recently he has made clear his fury at plans for the proposed 'Tobin' tax that would charge a fee for every financial transaction. In August 2011 he said such a tax would be prohibitively expensive, and that he was prepared to relocate ICAP out of the UK if European leaders pushed ahead with plans to introduce this financial transaction tax.

"This tax would destroy the City and cost the Exchequer billions, but it would benefit Brussels. Companies like ICAP will simply move elsewhere outside the EU if Nicolas Sarkozy and Angela Merkel push ahead with this silly tax."

Keeping the City sweet for the Tories

Before the last election the Tories and David Cameron were wary of being seen to be giving too many concessions to big business, against the backdrop of public outrage about greedy bankers. Spencer however told a meeting of business chiefs that 'the City should not be unduly concerned by his party leader's rhetoric on bankers. The Conservatives were "very, very well aware" of the importance of the City and "realise it has to be nurtured", he said.

Telegraph leader writer David Hughes blogged: "My hunch is that Osborne is using Spencer as an outrider to re-assure the City in particular that regardless of the state of the public finances, taxes will be lower under the Tories – and in particular that the hated 50p rate that kicks in on April 1 next year will be short-lived. We shall see."
