The peer who coined the phrase 'New Labour' left a six-figure sum to his beloved wife after tragically drowning while wild swimming.
Lord David Lipsey, 77, was found dead in the River Wye in Glasbury, Wales, on July 1 last year.
Lord Lipsey, who was also known as the Baron of Tooting Bec, was involved with the Labour party for decades and also came up with the phrase 'Winter of Discontent'.
He was secretary of the Labour Party in Streatham from 1970 to 1972, later going on to become an advisor to 10 Downing Street under James Callahan.
He came up with the name New Labour for the then-Prime Minister, Tony Blair, who would later grant him a peerage in 1999 that saw him sit in the House of Lords.
Lord Lipsey also coined the 'Winter of Discontent', referring to the winter of 1978-9, characterised by mass strikes and bitterly cold temperatures.
After his time in Westminster, he went on to become a successful journalist with roles at the New Statesman and the Economist.
On the day of his death, Lord Lipsey was reported missing after entering the water.
