JOIN USCameron's speech sparked a row even before it was delivered in Hampshire, when its text was released.
Noting the tough language in the speech, Business secretary Vince Cable termed it as 'very unwise' and said the policies outlined were not agreed within the coalition between the Conservative and Liberal Democrats.
Citing the abuse of student visa system that had prompted a tough stand on immigration, Cameron said: "Want to know how ridiculous things have got? An Indian organisation which helps people get student visas has put up a massive billboard in that country".
"It's got a picture of London bus and the words 'get a free ride to the UK' emblazoned across it".
Britain had suspended issuing visas in north India among places in south Asia last year when a large number of visa applications were lodged.
Immigration officials have launched a crackdown on bogus colleges in Britain that sponsor students on short-term courses who allegedly use the visas as route to entry into Britain.
Cameron mentioned several figures to substantiate his point that the visa system did not work during the previous Labour governments.
He said the coalition government was committed to bringing immigration down to "tens of thousands instead of hundreds of thousands" every year.
However, Cable said: "The reference to the tens of thousands of immigrants rather than hundreds of thousands is not part of the coalition agreement, it is Tory party policy only".
"I do understand there is an election coming but talk of mass immigration risks inflaming the extremism to which he and I are both strongly opposed".
Elections to local councils are scheduled for next month, when coalition partners Conservatives and Liberal Democrats will contest against each other.
Cameron's speech is seen as a pre-election exercise intended to appeal to Conservative voters.
Before setting out his government's policy in tough terms, Cameron lauded the contribution made by immigrant communities from the Indian sub-continent, and added that Britain now wanted "good migration, not mass migration".
He said: "Our country has benefitted immeasurably from immigration. Go into any hospital and you'll find people from Uganda, India and Pakistan who are caring for our sick and vulnerable".
