The resignation of David Laws over his use of expenses has caused sadness among the commentariat – more than any other expenses-related casualty. This has baffled some in the blogosphere, who believe he broke the rules and so had to go.
The first reason for grief is simple: Mr Laws was an exceptionally able man with a staggering sense of public spirit. He left a serious City job to work in the Lib Dem research department. He appeared, as George Osborne put it, to have been put on Earth to take a job at the Treasury. By contrast, when Jacqui Smith was caught out, few cared enough to defend the not-very-convincing home secretary.
