A bill for a new police squad was included in the speech

The Serious Organised Crime Agency (Soca), dubbed the "British FBI", will investigate drug and people trafficking, fraud and internet crimes.

The Home Office said the bill to create the force would also include a "radical" overhaul of police powers.

Further measures to crack down on drugs were included in a separate bill.

These changes would better equip both police officers and police staff with the necessary powers to fight crime Home Office spokesman

Soca, which will be made up of officers taken from existing agencies, will be headed by the former head of MI5, Sir Stephen Lander.

Its officers could be trained by the security services to track down key organised crime figures.

The Queen said: "Legislation will be introduced to establish the Serious Organised Crime Agency, and the powers the police and others have to fight crime will be strengthened."

A Home Office spokesman said the Soca bill would bring about a "radical" overhaul of police powers and would extend powers of community support officers.

"These changes would better equip both police officers and police staff with the necessary powers to fight crime and anti-social behaviour in communities and free up officers for frontline duties," he said.

The Queen's Speech contained no details of the overhaul, but a consulation paper published in August suggested extending the power of arrest to include all offences.

It said community support officers may be allowed to search people and enforce by-laws.

Law Society chief executive Janet Paraskeva said: "The police would have a power to arrest however minor the suspected offence. That is not an appropriate balance between the liberty of the citizen and the needs of the police."

Drugs Bill

Plans for new anti-drugs powers will come in a separate bill

A separate Drugs Bill would allow suspected offenders to be tested for drugs at the time of their arrest, rather than when they are charged.

It has been reported that the bill may also redefine "possession" of drugs to include substances found in the bloodstream, but the Home Office denied that it would be in the bill.

These plans are ludicrous and more posturing than policy Lord Adebowale Turning Point

But the Home Office said that was "definitely not" in the bill.

The bill would also double the amount of time officers can detain a suspected drug offenders in custody, so that drugs have time to pass through their bodies.

But ministers have scrapped a plan to allow police to X-ray against their will suspects who are believed to have swallowed or concealed quantities of drugs in their bodies.

Under the bill, judges would be able to tell a jury they can "draw an inference" if a suspect has refused a full body search.

Lord Adebowale, chief executive of charity Turning Point, said: "These plans are ludicrous and more posturing than policy.

"We need to focus on making current treatment programmes more effective, not dreaming up new offences to shovel people into the system."
