Don't put Ed Miliband in No 10 by default, Tory minister warns Coalition policies on those issues are dictated by the power-sharing deal with the Liberal Democrats that constrains Conservatives, he insisted: "There are 303 of us, and we are outnumbered by Labour and the Lib Dems." Tory supporters should remember that reality and not express their frustrations either by refusing to vote or by backing Ukip, Mr Grayling said. Doing either could hand a decisive advantage to Labour in 2015. "If you're naturally Conservative, but you're tempted by the lure of the sofa on polling days, or by the smooth patter of that nice Mr Farage, just remember the reality of what you are doing," Mr Grayling said. That message is also relevant to elected Conservatives, including those in Parliament, the minister said. Mr Grayling's comments represent a fresh focus on ensuring that the "core" Conservative vote actually turns out to support the party in 2015. Many senior Conservatives are worried that the party is losing too much support to Ukip, which is tipped by some analysts to finish first in next year's European Parliament elections. Mr Grayling, a leading figure on the Conservative Right, has been a strong supporter of David Cameron, and his article is his latest move to rally wavering traditionalist Tories behind the Prime Minister. Describing Mr Miliband as "the most Left-wing political leader this country has seen since Michael Foot," Mr Grayling urged colleagues to focus all the energy on delivering a Conservative victory over the Labour leader. "If Conservatives go into the next election divided, and our supporters drift somewhere else, we could let him into Downing Street by default," he said. A Labour-led government after 2015 might keep the Conservatives out of power until 2025, Mr Grayling suggested, warning of a "nightmare scenario for Britain" where Tory divisions let Mr Miliband rule "for five or even 10 years."
