Pop songstress Geri Halliwell has opened up about the criticism she faced after posting a tweet about the death of former British Prime Minister, Margaret Thatcher.

Thatcher died earlier this week, aged 87, and Halliwell joined thousands of others in expressing sadness over her passing via social networking site Twitter, but has explained in a blog post that she didn't expect such a backlash after describing her as "the first lady of girl power".

Halliwell writes: "Monday 8th April 2013 – Margaret Thatcher had died… I felt compelled to tweet my thoughts for a female leader, in a world governed by men. I was so confused and overwhelmed by some of the feedback I received that I took my tweet down and for that I was called spineless."

"I questioned myself? Did I really mean what I said? Can I stand tall? Do I even know what I was talking about? I realised the best thing to do was to shut up and really get honest with myself. What I hated the most was that I took a tweet down. I had wavered and was full of self-doubt."

After discussing the message she shared, the 'Wannabe' hitmaker concluded: "I was so afraid of upsetting people, and not being liked for saying something that was not to everyone’s taste. But now I realise that I do admire a woman, whether she is right or wrong, regardless of her opinions. She had the courage to stand by her convictions. Not like me. I look at my behavior, which exposed how weak I was under fire, not like Margaret Thatcher. Rest in peace."
