Wow how can I possibly follow Bhardra interpretation.....congratulations on a great job!
However here is what I see and just for the record I am using the Sharman-Caselli Tarot deck which is very closely related to the Rider Waite Tarot.

This king sits in all his splendour on a very rich looking throne. He is a strong leader as depicted by the Lions seated at the top of the throne. He is also very ambitious and is of a very competitive nature.
He is an excellent leader and a successful business man enjoying the fruits of his labour. He is full of charm and people admire and follow him. He is surrounded by two rams which show me that he is Aries. Aries to me is a very fiery sign, and this king will be a good friend to you however cross him and he will really fire up. He will not suffer fools gladly.
Can represent a male boss.
Maybe you will have some dealings with someone in a business way.
Again I this is another card that I have a lot of trouble with when I try to read the cards. I know what he is and what his character is like but when he comes up in a spread.....I am stuck!!!!
