A significant proportion of Cambridgeshire’s votes in May’s General Election are still up for grabs, a survey by this newspaper suggests.

With less than a month to go until the nation goes to the polls, almost one in five of those to take part in our online election questionnaire say their vote can still be swayed.

Meanwhile, four in 10 say they expect to vote differently than in 2010.

We asked visitors to our website a handful of key questions about the election, their vote and issues that matter to them. In total, 235 people responded – 62 per cent were male and 38 per cent female.

While 60 per cent said they were 100 per cent certain who they would vote for, 11 per cent said they ‘had an idea but my vote is still up for grabs’ and eight per cent that their ‘vote is definitely up for grabs’.

With some of Cambridgeshire’s seats expected to be on a knife-edge, those 19 per cent of currently unsure votes could become crucial on May 7 to determine which parties win.

Only 30 per cent said they believed the government has had a positive impact on their life since 2010, while 48 per cent said it had had a ‘negative’ impact. Those figures were considerably more positive than neighbouring Norfolk.

The figures suggest prospective MPs need to do more out on the streets of the region, with just seven per cent saying they had received a visit from a candidate, but 89 per cent said that they hadn’t. However, 85 per cent did at least say they knew who their MP was.

When asked what issue mattered to them most, there were two key areas that took the majority of votes: economy (23 per cent) and immigration (22 per cent) followed by health (13 per cent) and education (eight per cent).
