"Cameron's initiative is an exercise in presentation over substance and designed to blame foreigners and migrants for the failure of his Government," Kamaljeet Jandu said.
On Thursday, the newly reelected prime minister introduced a three-part legislative effort to curb rising immigration to the UK amid record figures for net migration.
The bill, due to be approved next week, seeks to make it a criminal offense for undocumented migrants to work in the United Kingdom and seize their wages "as proceeds of crime."
"Cameron does not want to provide resources to deal with this bad behavior of employers," Jandu told Sputnik of his views on the prime minister's plan.
Measures in the new anti-immigration bill include a "deport first, appeal later" clause, efforts to shut down so-called bogus colleges and a crackdown on "sham" marriages.
"He is creating a dangerous atmosphere of scapegoating those already very vulnerable and exposed," Jandu told Sputnik.
Cameron campaigned in this month's election on the promise to reduce annual net migration from outside the European Union to less than 100,000 people. The Office for National Statistics' data released on Thursday estimated that 318,000 more people entered the UK than left in 2014, the highest net migration figure since 2005.
Cameron's Conservative Party gained an unexpected majority in the 650-seat House of Commons on May 7.
