The battle-lines for the North Norfolk constituency look set to be re-drawn for the next general election.
The boundary review could see the seat gain Aylsham, but lose the village of Briston.
Proposals to cut the number of MPs from 650 to 600 were unveiled this week by the independent Boundary Commission.
Changes to Westminster seats will take years to finalise and implement ahead of the general election due in 2020.
Current MP Norman Lamb, whose majority at the last election was 4,043, will lose Briston and gain the market town of Aylsham in the shake-up, meaning he would be working beyond the North Norfolk District Council border for the first time.
Mr Lamb, who was this week re-selected to fight the seat, said: 'I am disappointed to lose Briston, but the addition of Aylsham makes sense. The town sees itself as belonging to north Norfolk – many of my constituents go there for shopping, the doctors and church.'
He added: 'This is the first time I have broken into another district council area, there may be reasons why people question that, but I don't think district council boundaries are the be all and end all.'
The constituency will swell from 67,000 to 71,657 voters if the plans go ahead.
UKIP candidate for North Norfolk at the last election Michael Baker said their performance in 2015 had been very strong.
He said: 'I am very positive, adding Aylsham is a huge bonus to the UKIP cause.'
Chairman of North Norfolk Labour Party Stephen Burke expressed concern that the proposals appeared to be more about benefiting the Conservative Party.
He said: 'We are surprised to find Aylsham could become a part of the local constituency, we had expected to see Fakenham return instead, which may have made more sense being part of the local district council area.
'We had hoped these proposals would end the blurred lines between what areas are Broadland and what are North Norfolk, but we don't think this has so far been achieved.'
