Meghan Markle could make a fortune from Instagram if she becomes a full-time influencer, according to an expert.

Axar.az reports the Mirror exclusively reported in March that Meghan plans to relaunch her lifestyle blog The Tig.

It's thought the lifestyle brand could take on Gwyneth Paltrow’s $ 250 million Goop empire and Kourtney Kardashian's $ 15 million brand Poosh.

Like Goop and Poosh, the revamped blog would offer tips on food, travel, fashion, the arts, design, conscious living and wellness.

The mum of two could also become a kind of agony aunt, according to details filed with the US Trademark and Patent Office.

Meghan founded The Tig, named after her favourite red wine, in 2014 while starring in the legal drama Suits.
