Tory leader blasted for dwarf quip

A charity which helps people with primordial dwarfism and other forms of restricted growth said the comments were a form of harassment – and called for talks with the Prime Minister.

In a dig at Mr Bercow – believed to be 5ft 6in tall – Mr Cameron said Health Minister Simon Burns had asked his driver to reverse into the Speaker's car. When Mr Bercow said he was "not happy" about the incident, Mr Cameron quipped at a Westminster lunch yesterday, Mr Burns retorted: "So which one are you?".

Mr Cameron's spokeswoman said he had made "light-hearted comments not intended to cause offence".

But John Connerty, co-founder and charity secretary of the Walking with Giants Foundation, launched a fierce condemnation of the Prime Minister.

"It appears that certain Government officials are above the law when making derogatory references and associations to a disability."
