Centre for London says numbers are falling and wants the government to step up to support the industry

Black cabs could disappear from London’s roads in 20 years, a thinktank has warned, unless authorities take steps to halt the decline – including giving cabbies bigger loans for new electric taxis and making the Knowledge test easier.

Centre for London said that if the number of taxis in the capital continues to fall at the current rate, there would be none left by 2045.
