A cross-party campaign is under way in Parliament and at City Hall involving MPs Sir Vince Cable, Zac Goldsmith, Ruth Cadbury, Mark Field and the Mayor of London, to resist any plans that threaten the viability of these passenger boats. Lord Salisbury, who organised the Queen’s Diamond Jubilee Thames pageant in 2012, and Lord Owen, the president of the River Thames Society, have written to Transport Secretary Chris Grayling asking him to urgently revise the Maritime and Coastguard Agency’s plans, warning they would “annihilate” the Thames boat sector.
