Tony Blair is heading for a second landslide on June 7, private polling released by the Labour Party claims.

According to the poll data, Labour is set to poll 46 per cent of the vote, with the Tories on 26 per cent and the Lib Dems on 16 per cent.

Should Labour retain a 20 point lead on June 7, the party would see its majority increased by 50 seats.

Labour claims that its polling evidence shows that William Hague's decision to focus on Europe and tax is not winning votes.

Millbank strategists say they will now shift the focus onto Labour's record on public services and the economy.

As the campaign enters its last week, the party will also focus on Blair's leadership, contrasting his style with that of Hague.

Alastair Campbell, the prime minister's press secretary, told the Press Association: "The only politicians with lower ratings are William Hague and Michael Portillo. We have to make the issue of leadership more than about just `Tony Blair is a nice bloke'. It's the importance of leadership to a government and a country."

Labour's private polling, conducted by NOP, also shows heightened interest in the election indicating that turnout may not be as low as initially predicted.
