THE Government has failed to protect Britain's borders and left the UK open to terror attacks, an ex-police chief has claimed.
Former Met Commissioner Lord Stevens says extremists could use small airfields to launch blitzes and hide bombs on cargo flights.
He also accused Whitehall of lacking a clear strategy to keep Britain's borders secure.
Lord Stevens said the UK's air cargo system could be infiltrated by extremists and that Britain could face terrorist threats for another 30 years.
He said: "The air cargo system is vulnerable to security threats.
"It includes plots to place explosives aboard aircraft, illegal shipments of hazardous materials, criminal activities such as smuggling and theft and potential hijackings and sabotage by persons with access to aircraft."
His report was commissioned by the Tories and pointed to evidence from last summer's attack on Glasgow Airport by Muslim terrorists - where no armed police were on duty - as proof of the poor security coverage.
Under the Tory plans, a new police force would be set up to patrol all airports, major seaports and the coastline.
