The Head of Political Polling at Opinium says the results of the run-off to be the future Conservative leader and British Prime Minister come as a 'surprise' as Conservative MPs in Britain chose former finance minister Rishi Sunak and Foreign Secretary Liz Truss since there was a lot of 'momentum' behind Penny Mordaunt in the past few weeks. However, Chris Curtis warns 'how uncertain things are at this stage'. 'Liz Truss certainly starts to contest as the favourite but we've seen the polls move up and down quite dramatically in the few weeks where those contests have been active so far' he adds, arguing that 'there's a big argument about what exactly it is the Conservative Party in modern day Britain should be standing for.'
