The claims come as it emerged that a clutch of former supporters of Michael Portillo are ready to declare for David Davis, the shadow home secretary and favourite for the top job. The Times claimed that Mr Maude, former health secretary Stephen Dorrell and Andrew Tyrie had met on the eve of this week's shadow cabinet reshuffle to decide which candidates they would and would not back. Mr Tyrie was Kenneth Clarke's campaign manager in the leadership contest in 2001, while Mr Dorrell and Mr Maude backed Mr Portillo.
