Some big business are, some aren't. In February 2016, representatives of 36 FTSE100 companies signed a letter to The Times calling for Britain to remain in the EU. But that means the other 64 FTSE100 companies did not sign it. About 200 companies have committed to the Remain campaign - but that is a minuscule proportion of the 5.4 million companies registered in the UK.

Some big businesses like the EU because they want to deal with one central regulatory authority. They can lobby for the kind of regulation they want and which they can comply with, but which their smaller competitors cannot. They also like the endless waves of cheap migrant labour that the EU's open borders bring.

Other representatives of big businesses are equally vocal about wanting Britain to leave the EU - for example, Peter Hargraves, co-founder of FTSE 100 company Hargraves Lansdown. Writing in the Daily Mail on 25th February 2016 Mr. Hargraves said, "[EU] red tape and regulations have stifled enterprise in the UK, not helped." He added that Britain should be "forging trading links with nations that have fast growth rates and dynamic economies. While we are in the EU we must wait on unmotivated, overpaid Eurocrats". He concluded by hoping that the electorate would "decide to leave this disastrous and stifling union" .

Small and Medium Sized Businesses (SMEs) are even less enthusiastic about the EU. 200 bosses of SMEs signed a letter calling for Britain to leave the EU because of a "constant diet of unnecessary regulations" from Brussels that raise costs, cut profits and force up prices. The letter concluded that, "We believe that our economy can do better without being held back by the EU, thus we should vote to leave". The establishment is desperate to stifle any dissent - in March, the British Chamber of Commerce's Director General John Longworth was forced to resign for stating his personal opinion that we should leave.

No one has so far been forced out of a job for saying we should stay in.
