LONDON (Reuters) - Prime Minister Boris Johnson's Conservative Party extended its lead over the Labour Party to 14 percentage points, up from 9 percentage points a week ago, an opinion poll by Survation for ITV's Good Morning Britain showed on Monday.
The poll put Johnson's party on 45%, up 2 points, compared to Labour's 31%, down 2 points, before Thursday's national election.
These headline figures are rounded to the nearest full point, which explains the discrepancy between the weekly increase in the Conservatives' lead and the change in each party's individual figure.
The poll also showed that 52% of respondents would consider voting tactically, versus 44% who said they would not.
The telephone poll of 1,012 respondents was conducted between Dec. 5 and Dec. 7. Respondents were read out the names of the parties and candidates that are standing in their own constituency.
