The Deputy Prime Minister spoke today about reinstating the train line between Oxford and Cambridge once called the "Varsity Line" and to be renamed the "Garden City Line" across what he dubbed "the brainbelt of Britain" and building five new towns there, along with five elsewhere.
And he is due to say in his leader’s speech that the Lib Dems would insist on the new garden cities as part of any future coalition negotiations. However no community would be forced to have them.
Today, in his question and answer question at the conference in Glasgow, Clegg said that stations would be built along the line where towns agreed to build up to 15,000 homes.
He said: "Garden cities are something I have been banging on about for years and Conservatives have been resisting for years. We are finally making some progress." He said the homes should be built in "a properly-planned sustainable way."
The pledge follows on from a row within the Coalition earlier this year over garden cities, when Clegg accused the Conservatives of adopting a nimby approach to house building. He is expected to talk about the housing crisis in his speech
In August he said that homeowners should get compensation if the cost of their homes fell as a result of any new garden city development.
