We are sending out a clear message that freeloading will not be tolerated

The move is intended to create a stronger deterrent to fare dodgers and will bring London into line with the national rail network, which is due to make a similar increase.

Ken Livingstone said: "Only a tiny minority of passengers fail to pay fares but those who do are cheating the vast majority of honest travellers.

"By doubling the penalty for travelling without a valid ticket to £20, and increasing the number of inspectors, we are sending out a clear message that freeloading will not be tolerated."

TfL has over 240 Revenue Protection Inspectors patrolling the bus and tram network.

This will rise to 290 by the middle of 2005.

They are supported by 1300 members of the Transport Operational Command Unit, which is funded by the Mayor and TfL and provided by the Metropolitan Police.

There are currently around 240 ticket inspectors working on the Tube supported by 750 operational police personnel.
