Nick Clegg should speak out
The Lib Dems should be leading the charge against Michael Martin. It is the kind of issue where the Lib Dems can emphasise their outsider status and come across as the party prepared to break up the cosy Westminster consensus. Considering the public disquiet about how MPs are using the expenses system, the Lib Dems would be onto a winner. MPs and the political parties are reluctant to criticise the Speaker because they fear the consequences. As Nick Robinson points out, individual MPs worry that they might not get called in debates and the Tories want to ensure that one of their own gets the job next time round.
