There was plenty of speculation that the gay marriage vote was not quite as free as the party leaders would have us believe, though Guido was not expecting MPs, including a government PPS, to put such allegations in writing. A cross-party letter lobbying the Lords does just that:

The allegation of coercion was signed by Jim Paice, Edward Leigh, Glyn Davies, Fiona Bruce, Richard Drax, Jim Shannon, Tim Loughton, David Simpson, Jim Dobbin, Karl McCartney, Steward Jackson, Therese Coffey, David Burrows, Gerald Howarth and Craig Whittaker.

The full letter can be read here.

Guido is sure the Tory whips loved that one…
