In the latest ComRes/Independent poll, the Conservatives have their highest-ever rating at 46% (up 2%), with Labour down 5% on 25% and the Lib Dems up 2% at 18%. Fieldwork was done well after the budget had time to sink in. This tracks well with the two YouGov polls that showed similar leads.
ConservativeHome is suggesting that this equates to a majority of 170 using the UK Polling Report model. Just a bit of fun!
