A quiet backwater in the fens, for centuries little changed in Wisbech. Now the population's grown by a third - largely because of the high number of East European immigrants; a big issue for voters here and right across the region.

Eastern European shops have sprung up in the high street - reviving the town centre. In one fashion boutique, the assistant is from Lithuania, so is her customer.

Watch the full report here:

It's not those who work that our poll suggests worry voters but those who don't - 57 % saying new arrivals shouldn't get benefits.

Tensions in the town were brewing but there's been some success in integrating newcomers - for example at community centres teaching them English. Our poll showed that 33% of people want to limit the number of low-skilled migrants.

Among younger voters the mood seems to be changing - especially on Europe.

Some immigrants - like Adriana - now call Wisbech home. To voters, immigration is a concern but it may not be the issue that turns the tide in this election.
