A ComRes poll on the EU referendum has revealed 48% of people in the Midlands would vote to leave the EU.
The research has revealed if people were to vote tomorrow, 44% would vote to remain in the EU.
The most important issue voters in the Midlands say will determine how they vote is control over the number of EU migrants entering Britain.
61% say this would be one of their three most important considerations.
This is followed by control over Britain’s laws (49%) and the economy (37%) and national security (36%).
Mr Cameron is holding key talks in Brussels in the hope of securing further support for his proposed EU renegotiation.
It comes after he and French President Francois Hollande agreed that the draft EU plans provide the "firm basis" of a deal.
