Parties of all colours are making a last dash to woo voters in the final hours before the polls open.

The Green Party sent deputy leader Amelia Womack to meet students at the University of East Anglia, where she said the party was on course to gain its largest vote share

'It can sometimes seem like politics is only something that happens in Westminster so it is important to get out there and meet people,' she said.

'The Greens are likely to have the largest vote share we ever have without gaining a number of seats, and people will not feel represented because of the voting system.' But she added: 'I think people are realising that if you do not vote for what you believe in then you will never get the politics you want.'

Meanwhile Eric Pickles joined Norwich North Conservative candidate Chloe Smith at the home of Paul Utting, 30, and Shelley Watkinson, 27, to discuss the Help to Buy scheme which helped them on to the property ladder.

He said parties had long expected voters to make a late decision, but that he was confident they were drifting towards the Conservatives.

'We always knew that it was going to be a tight fight, and the closer we get to election day the more we realise that actually we are talking about 80 to 90 seats where this is going to be decided,' he said.

'[In Norwich North] we need to retain the seat in order for Mr Cameron to remain in Downing Street so it's not unnatural that other parties have thrown everything they have at it.

Meanwhile the UK Independence Party launched its undecided voter campaign in Norwich South. The party said it would be driving a van around Norwich South for 10 hours a day up until polling day, visiting estates and the city centre.

Candidate Steve Emmens said: 'I hope this leads to the same favourable response we have received from our leafleting campaigns across the wards.'
