MPs have voted against changing constituency boundaries in England.
The vote was taken today, and means the Meon Valley seat, currently held by MP George Hollingbery, will remain in place.
Had the changes been made, a new constituency including Horndean and Fareham would have been created.
The plan would have seen the number of MPs reduced from 650 to 600.
The majority of MPs voted to delay the decision until after 2018, after Deputy Prime Minister Nick Clegg withdrew his party’s support for the plans.
Tory MPs lined up to attack the Liberal Democrats over their withdrawal of support, including Portsmouth North’s Penny Mordaunt, who said the Lib Dems’ ‘code of conduct’ amounted to ‘an eye for a coalition eye’.
‘The Liberals have exchanged their legendary sandals for flip-flops,’ she said.
