The widow of murdered father-of-three Garry Newlove took her seat in the House of Lords earlier as a Conservative peer.

Helen Newlove, who has been a forceful campaigner against anti-social behaviour since her husband's death in August 2007, wore the traditional ermine as she was introduced to the Upper House in a short ceremony.

Her full title was announced as Baroness Newlove of Warrington in the county of Cheshire, but she will be known more straightforwardly as Baroness or Lady Newlove.

After swearing her allegiance to the Queen she received a loud cheer from peers as she shook the hand of Lord Speaker Baroness Hayman on her way out of the chamber.

Lady Newlove, 48, has campaigned against drink-related violence since her husband was killed by a gang of teenagers. He died three days after being attacked outside their home and kicked "like a football" by a gang who had been vandalising his car.

Three teenagers were jailed for life for his murder.

Speaking when her peerage was announced in May, following the general election, she described herself as "really chuffed and overwhelmed" by the honour.

"I want to work hard to make a difference. I won't stop until changes are made," she said.

Now she has been introduced she can take part in Lords debates and votes, although it is not known when she will make her maiden speech.
