Paul Cottingham, the partner of Lord Michael Cashman, died yesterday (23 October).
Cottingham worked with a number of organizations aiming to further gay rights in the UK, such as the Kaleidoscope Trust.
He entered into a civil partnership with the former Labour MEP Cashman, his partner of over 20 years, on 11 March 2006.
And he died after a long period of illness, cancer, last night.
Alistair Stewart, acting executive director of the Kaleidoscope Trust, told GSN: 'It's with great sadness that we heard the news about Paul today.
