Those who are definitely voting to stay In were least hostile about Mr Blair, with a net rating of -4 per cent. These "Definitely In" voters are meant to be closest to his stance on the EU, but still likelier to distrust (46 per cent) than trust (42 per cent) him. There is similar scepticism among those toying with backing continued EU membership, with 54 per cent saying they doubted him - markedly more than the 36 per cent who didn't. This should worry Mr Blair most, as he would hope his pro-European warnings would harden up those toying with staying in, but most of them regard him with suspicion.
