Campaigning in Rochester today David Cameron has called for "some changes" to how the UK deals with immigration from the European Union.
Exactly what the Prime Minister has in mind remains to be seen, but a European Commission spokesman gave the impression Brussels was unmoved by the idea.
The Prime Minister will have the chance to put his case when he meets European leaders tomorrow.
ITV News Deputy Political Editor Chris Ship reports.
David Cameron and Michael Gove were both in Rochester and Strood today trying to head off the threat of another Ukip byelection victory.
The Prime Minister was in town to urge voters to give him "one last go" at renegotiating the UK's place in Europe, while Chief Whip Mr Gove said it was "very important to reach every voter in this constituency".

Michael Gove has said he is not worried about Ukip in the crucial byelection in Rochester and Strood.
Mr Gove said: "I'm concentrating on giving people the chance to have a Conservative MP here in Rochester and Strood, people have been denied that chance due to the current MP's defection.
"We're not contemplating defeat."
David Cameron has hinted at a major announcement on immigration policy as he visited Rochester and Strood ahead of a crucial byelection.
"Of course it is one of the most important issues in this election," he said. "We will be setting out further steps in the weeks ahead."
David Cameron has made his first foray into the crucial Rochester and Strood byelection with an appeal to voters to give him "one last go" at negotiating a better deal for Britain in Europe.
The Prime Minister - who is desperate to prevent another Conservative seat falling to Ukip's "people's army" - insisted that only he could deliver on his promised in/out referendum on membership of the EU.
With Tory MPs under instructions to make at least three campaign visits to the Kent constituency - and Cabinet ministers at least five - the Conservative high command is committed to do all it can to halt Nigel Farage's battle for the seat.
The upcoming Rochester and Strood byelection is being seen as a "must win" for the Conservatives.
The byelection was triggered by Conservative MP Mark Reckless' defection to Ukip.
ITV News Political Correspondent Romilly Weeks reports as David Cameron makes an early visit to the constituency:
David Cameron said "further action" is needed to establish more effective control of migration as he visited Rochester - the constituency where Tory defector Mark Reckless will stand for Ukip.
Reports have suggested that Cameron is considering a range of options to limit the number of EU jobseekers entering the UK, he will make clear to his European counterparts that he will campaign for a British exit during an in/out referendum if he does not get what he wants.
The Prime Minister is coming under intense pressure from Conservative backbenchers to make his negotiating position clearer ahead of the Rochester and Strood byelection on November 20.
