John Bercow's hopes of receiving a peerage were extinguished on Thursday night after he was publicly rebuked by the House of Commons and accused of using “sexually and racially inappropriate” language by his former most senior official.

After the former Speaker was admonished for naming former staff he is accused of bullying in his autobiography, The Telegraph can reveal that he is facing fresh claims of offensive behaviour.

Lord Lisvane, the former clerk of the House of Commons, is understood to have set out details of Mr Bercow making inappropriate remarks in an official complaint submitted to the Commissioner for Standards, the Parliamentary watchdog.

While Lord Lisvane declined to comment, senior allies have confirmed to this newspaper that his complaint goes beyond allegations of bullying and harassment to include examples of comments made by Mr Bercow in his presence.

It is the latest in a series of fresh allegations to be levelled at Mr Bercow since it was reported last month that he had been nominated for a peerage by Jeremy Corbyn.

A spokesman for Mr Bercow dismissed the claims as “unadulterated rubbish”, adding: “As Speaker [he] made constant efforts to increase diversity and inclusion. His record as a champion of gender, racial and LGBT equality speaks for itself.”

Meanwhile, senior Conservative sources claimed there was now “widespread opposition” among peers to Mr Bercow being elevated to the House of Lords.

And in comments that appear to extinguish Mr Bercow’s hopes of securing a peerage, a senior Parliamentary official said he had “no chance” of being handed one.
