Labour leader Ed Miliband has pledged "never again dismiss people's concerns about immigration."
"Britain cannot, should not, close ourselves off from those who can contribute to our economy and our country," he continued.
"But people do want to know there are fair rules".
Ed Miliband has claimed Britain is "a country of food banks and bank bonuses" as he set out Labour's stand for the General Election.
"They [the Conservatives] call that a success," Miliband told Labour supporters in Salford.
"Well I don't and the British people don't either," he added.
Ed Miliband has announced Labour will hold four million individual conversations with voters setting out their case in the run-up to polling day.
That will be almost double the number achieved at the last election in 2010.
Ed Miliband has said his party is "fighting for Britain" as Labour's General Election campaign got underway.
Ed Miliband has hit back at a Tory attack on his party's spending plans, saying the election will be a choice between "hope with us and falsehood from the Conservatives."
The Labour leader told BBC's Breakfast: "The Tories are saying that they want to go back to 1930s levels of public spending as a share of our national income, that's levels of national income not seen for 80 years or so in our country.
"I don't believe you can protect the NHS with that kind of plan. It's extreme, it's ideological and I think it will be really bad and damaging for our public services."
Setting out his plans for more integration between health and social care, Miliband insisted that Labour's proposals for a £2.5 billion annual funding boost would ensure the NHS is sustainable.
In case you wondered, this is what the General Election will sound like....
- Conservatives; only we can protect the Economy.
- Labour; only we can protect the NHS.
- Liberal Democrats; only we can protect you from those two.
- UKIP; only we can protect you from Europe.
- SNP; only we can protect Scotland.
- Greens; only we can protect the Environment.
The exciting thing is that no one, but no one, quite knows what the British electorate most wants protected, and we won't find out until the 8th of May.
Tony Blair has denied saying Labour leader Ed Miliband is too left wing to win the next General Election.
The former Labour prime minister told a magazine his party was "traditionally" defeated at the ballot box when presenting "traditional" left-wing policies against "traditional" right-wing opposition.
But Mr Blair took to Twitter to say the comments mis-represented his faith in Mr Miliband's ability to win the 2015 election, as ITV News Political Correspondent Emily Morgan reports.
Tony Blair says his comments about Ed Miliband's chances of winning a general election have been "mis-interpreted".
TB: "My remarks have been mis-interpreted, I fully support Ed and my party and expect a Labour victory in the election."
He had been seen as casting doubt on whether Labour can win the general election fighting on Ed Miliband's "traditional left-wing" platform.
The former prime minister's remarks, in which he acknowledged there was "obviously a difference" between his politics and those of the current leader, came as Mr Miliband appealed to voters ahead of May's poll by offering an economic recovery which "reaches your kitchen table".

Labour's shadow cabinet ministers should clearly set out how they will cut spending in their departments, Lord Mandelson has said.
The former Cabinet minister, one of the architects of New Labour, said the party had to position itself in the centre and not be swayed by the rise of "marginal parties" like Ukip.
Lord Mandelson praised Ed Miliband for speaking out on the deficit, but also indicated he would like to see the leader's older brother - and former rival - David return to British politics.
He told BBC1's Andrew Marr Show that the Labour leader and shadow chancellor Ed Balls had set out a "sensible and reasonable" position on reducing the deficit, but the rest of the party needed to back him up.
