ENVIRONMENTAL campaigners are using a 25ft purple boat to block a busy Glasgow city centre road, in protest against inaction on climate change.

Extinction Rebellion Scotland's vessel was placed in Trongate on Monday, covering the intersection of Gallowgate and High Street, by the Merchant City clock tower.

The boat carries a message from the group which says Act Now, understood to be a demand for the UK Government to do more to tackle the climate crisis.

A message saying "the future you fear is already here" is on the other side of the vessel.

Glasgow City Council said the Trongate was closed to all eastbound traffic between Albion Street and High Street due to the continuing protest.

The local authority urged road users to consider taking other routes and warned there could be some congestion on surrounding streets.

Extinction Rebellion protests were also to take place in Bristol, Cardiff, Leeds and London.

It comes as part of the group's week-long "summer uprising".
