Should there be a rise in National Insurance?
Another 14 business leaders say they are backing the Conservatives' plans to abandon the government's proposed rise in National Insurance. Do you agree with having a NI increase?
The latest group joins bosses of 23 other major companies, who warned the government that putting up National Insurance would endanger the recovery.
Mr Cameron tells BBC Radio 4's Today programme that halting the tax increase is not in conflict with his party's plan to cut Britain's record budget deficit.
Will halting the tax increase work? Do you agree with the 23 business leaders? How do you think Britain's budget deficit can be cut? Are you a business person? If so, what is your view? Is this a "significant" moment in the election campaign?
