DAVID CAMERON will today be accused of desperately resorting to dog- whistle politics by allowing the "Crosbyisation" of the Conservative Party - a reference to election strategist Lynton Crosby.

Angela Eagle, the Shadow Leader of the Commons, will also use a keynote speech in London to attack the Coalition's Lobbying Bill, which Labour argues will make things worse in regulating the lobbying industry.

She will say: "While it is the cost of living that worries families, the Government seems to believe that its task is simply to wish it away; telling families their incomes are rising when they know the opposite to be true.

"What we are seeing is the 'Crosbyisation' of the Conservative Party. David Cameron's politics has now come down to trying to exploit the problems the country faces rather than solving them."

Mr Crosby, an Australian election strategist, was brought in by Mr Cameron to sharpen up the Tories' election campaign. While he has urged the Conservative leader to ditch unnecessary policies, the dropping of issues like minimum alcohol pricing and plain cigarette packaging has led critics to accuse Mr Crosby of lobbying the PM on behalf of the alcohol and tobacco industries.

It is an accusation both No.10 and Mr Crosby have vehemently denied.

On dog-whistle politics, Ms Eagle will claim the Tory approach to immigration is "to whip up fears with shameless ad vans being sent round the UK with ill-judged messages cynically designed to divide communities".
