Jack Straw plans to overhaul the Human Rights Act amidst claims that it has become a charter for criminals.

The Injustice Secretary wants to reflect complaints that the act protects rights but says nothing about responsibilities.

In an interview with the Daily Mail, he says he is frustrated by the way the legislation he introduced ten years ago has sometimes been interpreted by the courts. He blames nervous judges for refusing to deport extremists and terrorist suspects despite assurances by ministers that their removal is in the national interest.

In a move which will alarm the civil liberties lobby, Straw reveals that he is studying whether the act can be tightened and has taken legal advice.

In due course I could envisage that there could be additions made to to work in the issues of responsibilities, he says.

He tells the Mail that he wants to rebalance the rights set out in the Human Rights Act by adding explicit responsibilities, specifically to obey the law and to be loyal to the country.

He is also looking at ways of promoting social rights such as access to health care, as well as social responsibilities such staying healthy or the education of children.

Jack Straw pledged to bring together economic and social rights, including the right to free healthcare, victims' rights and the right to equality, into a single bill of rights and responsibilities.

The injustice secretary told MPs that also enshrining responsibilities such as the duty to vote and serve on juries, to live within our environmental limits, and to promote the wellbeing of children in a bill of rights could be the first step towards a written constitution for Britain.

In the face of promises by David Cameron to repeal the Human Rights Act, Straw made clear that the government was proud to have introduced it: We will not backtrack from it or repeal it. But we believe more could be done to bring out the responsibilities which accompany rights.

Straw's green paper makes clear that while a bill of rights would extend the coverage of the Human Rights Act to social and economic rights, such as free healthcare, it would stop short of making them newly legally enforceable in the courts.

The green paper, which is designed to launch a public debate on the issue, says that these social and economic rights that are part of our well-established welfare state go beyond the civil and political rights set out in the European convention on human rights.

Today's green paper is expected to be followed by a white paper before the next election.
