Campaigners calling for car-free zones in London have today staged a protest outside the headquarters of Transport for London (TfL).
Members of campaign group Climate Rush kicked off proceedings with a "go-slow" cycle across Blackfriars Bridge, before riding over to TfL.
The protest was held to mark World Carfree Day.
Climate Rush's Andrew Tobert said: "Imagine if cars were banned from central London. Buses would glide through town, people would feel safe cycling and our air would be clean. Children could walk to school."
He added: "Instead, we have inefficiency. We have time being wasted and lives being lost."
The campaigners are calling for car-free areas and 20mph restrictions across the centre of the capital.
But Leon Daniels, a spokesman for TfL, responded that the organisation had invested millions of pounds in improving London's streets for cyclists.
Daniels was also keen to point out that London mayor Boris Johnson is an enthusiastic cyclist and has made a "cycling revolution" his "key priority".
In May this year, more than £4m was awarded to London boroughs to improve cycling routes. Councils were awarded the money after making bids for funding that pledged to put cycling at the heart of local transport plans.
Awarded boroughs included Croydon, Bexley, Brent, Ealing, Haringey, Hillingdon, Hounslow, Bromley, and Kingston.
Daniels also pointed out that TfL is only responsible for a fraction of London's road network and that most responsibility lay with borough councils.
