Sir Jeremy Heywood criticised over 'plebgate' investigation

Downing Street has defended its investigation into the Andrew Mitchell affair, saying it believes the review was "exactly the right one".

Mr Mitchell resigned in October after allegedly calling a Downing Street policeman a "pleb", which he denies.

No 10 said the inquiry's scope was sufficient, after Cabinet Secretary Jeremy Heywood admitted he did not look at whether the word "pleb" was used.

Sir Jeremy was appearing before the Public Administration Committee.
