Britain can introduce a points based immigration system while still having access to the single market, according to Boris Johnson.
The prominent Vote Leave figure spoke out amidst calls for Leave campaigners to set out a clear plan after a win of over 17 million votes led to their victor.
In his Telegraph column , Mr Johnson sought to reassure voters of the UK's access to the free market and said cooperation with the EU will "intensify", although he told Leave supporters the win was "not entirely overwhelming".
He also added the "only change" will be "that the UK will extricate itself from the EU’s extraordinary and opaque system of legislation" and quickly pointed out the difference will not come into play quickly.

He wrote: "We must pursue actively the one-nation policies that are among David Cameron's fine legacy, such as his campaigns on the living wage and life chances."
Seeking to unite a divided nation, he continued: "We must reach out, we must heal, we must build bridges – because it is clear that some have feelings of dismay and of loss and confusion."
Other names mentioned in the Conservative leadership challenge include Home Secretary Theresa May, who is expected to announce her decision to stand against Mr Johnson in a matter of days.
Chancellor George Osborne and Michael Gove have also been highlighted by bookies, who favour Mr Johnson as most likely to be Britain's next PM.
