Her most recent book, Strong Woman, published in March 2012 and aimed at inspiring women in business, was a Sunday Times Bestseller.

"[23] Sullivan later commented that he agreed to the deal because such a young, female director would attract publicity to the club, and also because Brady was a “sacker”.

Writing in her newspaper column Brady said "To West Ham fans I'll make a single pledge – while we are on the board, we will hang in the Tower of London before your club again goes through the financial turmoil which so nearly brought it down".

"[32] Brady was responsible for negotiating a move on behalf of West Ham United from their Boleyn Ground to the Olympic Stadium in Stratford, east London.

[33] Investigators working on behalf of Tottenham were subsequently charged with fraud for obtaining illegally the private telephone records of Brady.

[34] In December 2012, West Ham were announced as the highest ranked bidder to become the anchor concessionaire and tenant of the Olympic Stadium.

[36] In July 2013, Brady gave evidence before a House of Lords committee, where she said the club has debts of £70m that would need to be paid before the proposed move to the Olympic Stadium in 2016.

Subsequently renamed as London Stadium, the move saw West Ham United increase their capacity from 35,000 to 57,000 seats – which were completely sold out before the start of the 2016–17 campaign,[38] giving the Club the third biggest home attendance in the Premier League.

[39] Following the move to the Olympic Stadium, some supporters who wanted to stay at Upton Park targeted verbal abuse towards Brady and other board members during crowd disturbances during West Ham's home 2–4 defeat to Watford on 10 September 2016.

[40][41] In October 2016, Brady received further criticism after describing West Ham's move to the London Stadium as "a chance to rebrand the club".

[44] She was a non-executive director of Channel 4 television[44] but resigned to take a position at Syco, the company jointly owned by Simon Cowell and Sony.

In September 2010 she joined the board of Taveta Investments Ltd.[15][45] with Sir Philip Green, resigning from a non-executive position with Mothercare where she had been for seven years.

“It is critical to create opportunities to identify talented women in business, then support them to develop their confidence to aim for the boardroom.

We need to look outside the corporate mainstream, at female entrepreneurs and self-employed businesswomen, who can inject different insights and diversity to any board.”[48] Similarly, Brady famously told the Independent: "If you don't have a woman on your board you should write to your shareholders and explain why.

[51] Brady was appointed Commander of the Order of the British Empire (CBE) in the 2014 New Year Honours for services to entrepreneurship and women in business.

After the show, it was revealed that Brady had fulfilled a promise she made to Lord Alan Sugar on screen, and offered a job to Claire Young, who finished as runner-up in the series, after being impressed by her interview.

The feature also suggested that Brady should be made a peer to bring more women into politics and to resolve the UK's financial problems.

[61][62] In February 2019, the Daily Telegraph reported that she was facing questioning about her role in non-disclosure agreements (NDAs) relating to allegations of misbehaviour on the part of the businessman Philip Green.

[67] In 2006, Brady underwent a full-body MRI scan as part of a medical screen, which unexpectedly discovered a potentially fatal cerebral aneurysm.

[68] Doctors told Brady at the time that she had a 30 per cent chance of dying from the condition, and that it was a miracle that she had survived the births of her two children.
