A new legislative map with 600 parliamentary districts instead of 650 was released this week. Some members of Prime Minister David Cameron's Conservative Party have said they may oppose the plan when it comes up for a vote in the House of Commons in 2013, the Financial Times reported.
Cameron's coalition partners, the Liberal Democrats, are angry because 10 of the 43 seats the party now holds in England would disappear.
"There is a significant chance that the disruption in all of this will persuade the coalition partners to kick it into the long grass," one Conservative legislator whose district would be dissolved said.
Business Secretary Vince Cable, a Liberal Democrat, suggested the plan put too much emphasis on having districts with roughly similar population instead of considering their identities. Under the plan, no district is supposed to have a population more than 5 percent larger or smaller than average.
Kevan Jones, a Labor member of Parliament, told the Daily Mirror the Liberal Democrats are getting what they deserve.
"Lib Dems deserve no sympathy over this," he said. "They voted and signed up to it in the Coalition agreement."
