And they have drawn up a list of key demands to reduce the risk of another London Bridge bloodbath.

Spooks are calling for:

Electronic tags to be worn by hundreds of "nominal" terrorists high on watch lists to track or limit their movements.

A total ban on the sale of unregistered SIM cards to stop terrorists communicating. Buyers will be required to provide concrete proof of ID.

A ban on immediate vehicle rentals. All renters to be required to provide proof of ID and have their details run through the police national computer. They will have to wait at least two hours while their details are checked.

Demand for a crackdown on Twitter. Crowing messages supporting the attackers were posted this morning including one which had 12,000 likes. Twitter to be asked to set up more content filters.

Increased resources for the 0800 anti-terror hotline with speakers of Pashtu, Punjabi, Arabic, Farsi and Urdu drafted in. Recommended that callers with terror tip-offs should be assured conversations will not be recorded.

A security source told The Sun last night: "The measures being drafted will not be to the liking of civil liberties groups.

"But this crude attack has led to a rethink of how the security services monitor and track people plotting to do us harm.

"They want these measures - but it will be up to whichever party wins power on Thursday to decide whether they are implemented."
