There will be a parade, candlelit vigil, Gay Village Party and youth pride event.
“When brands like Virgin Atlantic and Virgin Holidays are able to carry a message across the globe in support of LGBTQ+ people it is extremely powerful, and I am confident that we will work together over the next three years to drive real change both here in Manchester and around the world,” said Mark Fletcher, chief executive of Manchester Pride.
