"What is essential now is that we move on from the divisions that have preoccupied the UK since the Referendum in 2016 and work together to carve out a new future for our country, and new trade agreements with our EU and other potential trading partners."

Northern Spire bridge, Fulwell Mill, Seaburn Lighthouse, Keel Square, Market Square and High Street West will all be lit red, white and blue from dusk until dawn on Friday, with the exception of Seaburn lighthouse where the lighting is switched off at 10.30pm.
