The Conservatives have unveiled radical proposals to put more than 850 extra police on the streets of Sussex by scrapping the Government's asylum system.

Tory leader Iain Duncan Smith wants to introduce a strict quota on the number of immigrants allowed to enter Britain - saving up to £1.7 billion per year.

The Tories say they would spend a significant chunk of the cash on recruiting new police officers, increasing the number in Sussex by 852 over eight years.

A party spokesman said: "If we are to tackle criminality and disorder effectively, we need far more police officers for Sussex than are currently being proposed by the Government."

Mr Duncan Smith would only grant 20,000 asylum seekers permission to remain in the UK each year and establish a system based on determining applications before the applicants reached Britain.
