Lingerie entrepreneur Michelle Mone has taken her seat in the House of Lords.

Wearing the usual red robe, Baroness Mone of Mayfair was flanked by supporters Work and Pensions minister Lord Freud and Tory peer Baroness Morris of Bolton for the short introduction ceremony.

She swore the oath of allegiance to the Queen before a crowded chamber and packed public gallery ahead of question time in the Lords.

Lady Mone founded the bra and underwear business Ultimo Brands in 1996 but announced she had left the firm in August as her political and other business interests grew.

The 44-year-old, who grew up in the east end of Glasgow, has been appointed by the Prime Minister as a business tsar with special responsibility for start-ups and will sit on the Conservative benches.

Lady Mone is one of 45 new peers announced by David Cameron in August. Over half the new intake are Conservatives prompting accusations of "cronyism" from critics of the appointment process.

The growth in the size of the Lords to over 800 members has sparked fresh demands for reform of the upper House.

Earlier Lord Gilbert of Panteg, deputy chairman of the Conservative party and director of campaigning in the 2015 general election, also took his seat in the Lords.

He was flanked by Lord Taylor of Holbeach and Lord Cooper of Windrush as he swore the oath of allegiance to the Queen.
