Flight delayed by climate change protester bbc.com

Extinction Rebellion activists say they want to "shut down" London City Airport for three days.
BBC Newsnight's Nicholas Watt said his flight was about to take off when a protester refused to resume his seat.

Meanwhile, police made several arrests as activists blocked the main entrance to the airport, with some gluing themselves to the floor.

In Westminster, tents and protesters have been cleared from the roads leading to Parliament Square.

However, streets around Parliament and Whitehall remain closed to traffic, apart from cyclists, with a heavy police presence in the area.
