The Deputy Mayor of London’s visit to Medway next week has been cancelled.

Victoria Borwick was due to travel to the Towns for talks on a Thames Estuary airport with the head of Medway Council, Cllr Rodney Chambers on Thursday, November 22.

Her boss Boris Johnson is a vocal supporter of the idea, which would have far-reaching effects for Medway and the rest of Kent.

A council spokesman said an alternative date in the New Year was being sought.

The government has established a commission to decide how to expand the country’s aviation capacity.

It will issue its final report in 2015, although interim findings are due to be released by the end of next year.

A poll published yesterday found that almost half of MPs (46%) back a third runway at Heathrow – an option the Conservatives ruled out in their 2010 election manifesto.

By contrast, just 16% back a Thames Estuary airport.
