Six regional airports in the UK will temporarily reintroduce restrictions on carrying liquids over 100ml, the Department for Transport has said.

The change will come into effect from midnight on Sunday, and will affect passengers travelling from London City, Aberdeen, Newcastle, Leeds Bradford, Southend and Teesside airports.

All of the airports have Next Generation Security Checkpoints (NGSC) in operation, which had allowed them to scrap the rule. The hi-tech CT scanners create a 3D image of what is inside passengers’ bags.

The 100ml rule was introduced in 2006 after a foiled terror plot to blow up planes flying from London to the US with homemade liquid bombs.

A DfT spokesperson said: “This temporary move is to enable further improvements to be made to the new checkpoint systems and will only affect a small number of passengers.

“For most passengers, security measures will remain unchanged.

“Passengers should continue to check security requirements with their departure airport before travelling.”
