Lib Dem warns rebel Tories of 'consequences Sir Menzies Campbell, the former Lib Dem leader, warned that his party would not "simply form up" to vote for the Conservative-backed proposal for fewer Westminster seats. In a BBC interview, he suggested that Lords reform and the new boundaries were linked, meaning that if Lords reform failed, the boundary review would also fail. There will be a lot of hard talking going on. I don't regard it as a threat - I think these are two prongs of the same agreement, and I expect the first to be honoured, and I expect the second to be honoured as well," he said. The proposed new boundaries could cost the Lib Dems several seats, and Sir Menzies said that Conservatives could not depend on his party's support. "If you're a Liberal Democrat Member of Parliament whose seat has been carved up as a result of the proposals for a review of the boundaries, then the idea that you would simply march into the lobbies in support of the Conservative government's particular anxiety to obtain this piece of legislation is one which may be very hard to swallow," he said. The setback for Lords reform has even angered Lib Dems who had supported the Coalition deal. Jeremy Browne, a Foreign Office minister, attacked Conservative MPs who refused to support the Lords reform, which he said was a central part of the agreed Coalition programme. "I think there are some Conservative backbenchers who behave as if they did win the general election," he said. However, Stewart Jackson, a Tory backbencher, suggested that failure to back the boundary review could break the Coalition. He wrote on Twitter: "Memo to bolshy Lib Dems: Break deal on boundary changes and you'll be out of government. That vote has consequences too. Harriet Harman, Labour's deputy leader, defended her party after it was accused of playing games by threatening the Government with defeat over procedure while claiming to support the principle of the reforms. She said Labour had concerns, but added: "The people who want to undermine the Bill are Tory backbenchers who are using it to have a go at David Cameron and the Coalition."
