Sir Andrew said: “City Hall has been less than frank about what is going on.

“The general public have no idea of the extent to which immigration is driving
the city’s housing crisis and causing Londoners to leave.”

He added: “The business lobby seem to have a lofty disregard for the lives of
ordinary Londoners. It is ludicrous for them to suggest that London needs
immigrants on anything like the present scale.

“The inevitable effect is massive pressure on schools and hospitals and,
especially, on housing. London needs skilled migration, not mass migration.

“Those who promote the idea of an international city effectively free of
constraints on immigration seem to be blind to the implications for the
existing population of London.”

Migrationwatch said immigration would continue place huge demand on the
capital’s housing stock.

City Hall did not comment on the report’s findings.
