Please answer a question about the following article about The Sun (United Kingdom):

During the campaign for the United Kingdom general election, 2010, The Independent ran ads declaring that "Rupert Murdoch won't decide this election – you will." In response James Murdoch and Rebekah Wade "appeared unannounced and uninvited on the editorial floor" of the Independent, and had an energetic conversation with its editor Simon Kelner. Several days later the Independent reported The Sun's failure to report its own YouGov poll result which said that "if people thought Mr Clegg's party had a significant chance of winning the election" the Liberal Democrats would win 49% of the vote, and with it a landslide majority.

Who showed up on the editorial floor of the Independent?
James Murdoch and Rebekah Wade
