Organisers of a climate change protest which caused "traffic mayhem" in Canterbury city centre have hailed the demonstration a success.

Around 100 protestors from the group Extinction Rebellion campaigned in the city - blocking St Peter's Place and stopping traffic around the Westgate Towers in a bid to raise awareness of global warming.

Campaigners stopped traffic by standing in the road for seven minutes at a time with banners and giving speeches to motorists about climate change.

Eyewitnesses say the protest caused "traffic mayhem" as the protestors halted traffic at regular intervals.

The demonstration ended shortly after 2.30pm.

Nicholas Thurston, a spokesman for Extinction Rebellion Canterbury said the protest was a "success".

He said: "There was a really friendly atmosphere and so many people showed us support.

"The police were really pleased with how it went and the protest was really peaceful - only one or two drivers got really frustrated.

"There were two aims of the protest today. We wanted to raise this level of concern with the government and also make people aware so they can raise their voices too."

Elsewhere, demonstrators linked to the international movement have glued themselves to the gates of Buckingham Palace and staged mass sit-ins at the entrance to Downing Street.

With leading scientists saying there are only 12 years to limit climate change to 1.5°C, it is calling on local, regional and national government to urgently commit to bringing down carbon emissions.
