Ministers have pledged to close a legal loophole which prevents them reviewing soft jail terms for hate preachers such as Anjem Choudary.
There was outrage last week when Choudary was given a five-and-a-half-year term for inviting support for the so-called Islamic State of Iraq and the Levant (Isil).
He was convicted at the Old Bailey after backing the group in an oath of allegiance published online.
Under good behaviour rules, Choudary, 49, could be released after serving half of that term – just 33 months. Yet despite receiving scores of complaints about his sentence, ministers are powerless to do anything.
