In their election manifesto, published yesterday, the party's leader Tim Farron said that the Lib Dems' Green Transport Act would include a raft of measures aimed at improving air quality, many of which target private and public transport.
Mrs Bunting said: "These plans would build a brighter future for people in Newbury and West Berkshire and reverse Conservative cuts to our schools, hospitals and police".
The party also pledged a 1p increase on income tax and promised to spend the cash on 300,000 new homes and the education budget.More news: Tim Cook spotted testing Apple's glucose monitor
