Wayne Thomas, general secretary of the National Union of Mineworkers (NUM) in Wales, did not travel to London, says he still feels anger towards Baroness Thatcher, but has said that a debate on her policies should wait until after she has been laid to rest.
As a 22-year-old miner based in the Swansea Valley during 1984, his experiences of a year on strike have left an indelible mark.
Mr Thomas believes that the only fitting epitaph for Baroness Thatcher's grave would be "May God Forgive Her".

My view on the matter is quite clear - I do think that we should show respect for the family of Mrs Thatcher. They have lost a loved one.
There are grieving family members and we should respect that.
I think it has reopened the debate on the rights and wrongs of what she did. But that is a debate for after she has been buried.
I do think that people are trying to airbrush away how horrendous her policies actually were.
In Scotland former miners reflected on the "hated" figure's legacy locally.
At the Dean Tavern in Newtongrange, Midlothian, the funeral was shown on a television screen in the corner of the room.
The volume was turned off and none of the patrons in the bar appeared to watch the footage.
Instead, a 1980s documentary about the village, following the closure of its Lady Victoria colliery was played at full volume on another screen.

I'm not watching that funeral. I'd rather go and fight in Afghanistan.
– John Byrn, tavern manager
I think the world's a better place today. I'm glad to think that perhaps it's closure for a lot of people.
I think we're still suffering from (Thatcherism) today. The current banking system was started by her, she initiated all of that.
I think the economic crisis we're suffering today is largely down to the changes that she introduced.
The loss of industry in Scotland was horrendous. What did we not lose?
Hundreds have gathered at Goldthorpe Union Jack working men's club in Barnsley to give their own send off to Margaret Thatcher. They have arranged a party and later will burn an effigy of the former Prime Minister. The area is home to many former miners.

As Prime Minister, Margaret Thatcher faced overwhelming odds. The truth is that she saved us from economic disaster and turned Britain once more into an engine of economic progress. For this we must treasure and honour her memory.
