Mccartneys Taste-test All Linda's Frozen Goods

The vegetarian brand was launched by the former Beatle's late wife Linda in 1991, and, 10 years after her death (98), her family still takes an avid interest in the brand in a bid to maintain the same high standards Linda expected when she started the venture.

Daughter Mary, 38, says, "It's really personal to us because it is carrying on mum's message. We know what she would and wouldn't have wanted."

The Yesterday singer adds, "Nothing goes through without the MCCartney say-so. It has to, because it's our name on the packet."

Linda MCCartney lost her battle with breast cancer in 1998, aged 56.
