Prime Minister David Cameron promised "the best of both worlds" on Wednesday as he made his final appeals to voters in Thursday's referendum to remain in a reformed European Union.
Cameron told BBC Radio 4 he rejected "the idea you have to choose between being a success in the European single market of 500 million and campaigning to have jobs and wealth created by trading with other economies."
"You don't have to choose, you should do both," he told the broadcaster in a telephone interview. "The vision of Britain in Europe is, we do have a special status; we have the best of both worlds."
Cameron said he had "set out a very positive case that we're stronger, safer and better off if we stay."
The Leave campaign has focussed on EU migration in the last few weeks, but Cameron said Britain could not "solve our immigration problem by leaving the European Union."
He said he wanted to re-examine EU freedom of movement after negotiating concessions in February that allow Britain to restrict payment of welfare benefits to some EU migrants.
"We are reopening the freedom of movement directive because of the renegotiation, and we're getting changes on criminals, on third-party national, on sham marriages; on a whole set of issues that have come out of court judgments frustrating the United Kingdom," Cameron said, adding that "reform continues on Friday."
He gave several interviews to newspapers and visited a company selling skateboards on Wednesday.
"If you're still not sure, I say, don't take the risk of leaving," Cameron said in a message to readers of the popular free tabloid Metro. "Choose strength, safety and prosperity - today, and for many years to come."
In a counter appeal, Vote Leave co-leader Boris Johnson told Metro that the EU was "undemocratic, bureaucratic and unrepentant for its failings."
"Tomorrow you have a once-in-a-lifetime opportunity to take back control," Johnson said. "To lift our eyes beyond the strangulation of the EU, to cooperate and trade not just across the European continent but with the rest of the world."
