New British opinion polls show the main opposition Conservative Party is on course to oust Prime Minister Brown's governing Labour.
Two polls published on Wednesday show the opposition Tories hold a clear lead over Brown's party ahead of a national election which must be held by June 2010.
Ipsos-Mori found the Conservatives at 43 percent and Labour at 26 percent.
An ICM survey published in The Guardian newspaper gave the Conservatives 44 percent and Labour 27 percent.
The figures would give the Conservatives a majority of more than 100 House of Commons seats if replicated during the national election.
Ipsos-Mori interviewed 996 adults by telephone, while ICM interviewed 1,002 adults. Both polls had a margin to error of around plus or minus three percent.
