In the latest of our constituency reports from around the Anglia region we look at Peterborough, one of our fastest growing cities.
Peterborough has had a Conservative MP for a decade now but was Labour before that.
So the Tories are defending a majority of nearly 5,000 which would need a swing of more than 5% for Labour to win it back.
But the seat has seen some very close elections - the Conservative winning by just 3 votes in 1996.
Peterborough is also one of our most multi-cultural cities with challenging population pressures.
