He founded his own parties from the proceeds of the sale of a house in Hampstead, North London which he moved into in 1969 but stopped paying rent on in 1984; remaining there as a squatter. He made a profit of £710,000 on the sale of the house in 2004 after HM Land Registry awarded him ownership of the property. He is proposing a "preferendum" where voters choose individual policies from amongst those offered by each of the major parties.
He was for many years the neighbour of comedian Peter Cook and released an album of some of his personal home recordings featuring Cook under the title Over At Rainbows after Cook's death in 1995. The recording features a few of the notorious phone conversations between LBC radio's Clive Bull and Peter Cook under the guise of a Norwegian fisherman called Sven, many of which were made from George's home.
In July 2006, Weiss disclosed on the Clive Bull radio show that he had about £50,000 remaining from the windfall, however by February 2007 he was giving the more ambiguous description of "somewhere under £50,000". Also during February of that year, Weiss announced he was standing as a candidate in the local Belfast by-elections and was subsequently banned from appearing on the Clive Bull show until they were over.
Weiss was a candidate at the Brent East by-election in 2003, won by Liberal Democrat Sarah Teather, where he came bottom of a list of 16 candidates with just eleven votes.
The Vote for Yourself Rainbow Dream Ticket election record was then "surpassed" at the 2005 General election when British model Catherine Taylor-Dawson stood for the party in Cardiff North and achieved a single vote, though not from Taylor-Dawson herself, who wasn't eligible to vote in that constituency. Weiss himself set a new election record by simultaneously standing in 12 constituencies, beating Tom Keen of the Campaign for a More Prosperous Britain's previous record of 10.
He stood in all four Belfast constituencies during the 2007 Northern Ireland Assembly election. Standing for his Make Politicians History Party, he came third last in South Belfast and last in the three other constituencies with a total of 221 first preference votes. Sinn Féin leader Gerry Adams gave him a sixth preference vote in West Belfast.
On August 13 2007 George phoned in and revealed his plans for London in the year 2020, which included turning the M25 into a "wonderwall" and London becoming "the party capital of the world", financed by "the bank of a zillion wonders" in which every one would be an account holder and "the wonder" would be the base currency with a rate of one hundred "gasps" to the "wonder".
"Rainbow George" also calls BBC London 94.9 a lot at night-time.
On the 13th and 20th October 2007, and more recently the 12th July 2008, Rainbow George appeared on The Russell Brand Show on Radio 2 in order to publicise his political agenda, inviting Brand to take leadership with the party (of which Brand was sceptical) and announcing an online petition requiring 1,000,000 votes in order for the party to become recognised as a serious candidate in future elections.
