Deputy Prime Minister Nick Clegg has hit back at Lord Sugar on his weekly LBC radio show after Sugar declared he was an "embarrassment to the coalition" on Twitter over the weekend.
Clegg had suggested that wealthy pensioners should not receive perks such as free bus passes and winter fuel payments.
Lord Sugar disagreed and sent the following tweets expressing his thoughts on Clegg's ideas:
"He's slightly thin-skinned. He drives around in this great big Bentley on primetime television, he wafts around the House of Lords in ermine, and then he seems to be very offended when I point out that he has got a bob or two. I don't see why someone like him should be entitled to a winter fuel payment."
Clegg added that now that he's responded to Lord Sugar, he's sure he'll get "another torrent of classic Sugar tweet-abuse this morning." Sugar has yet to respond.
David Cameron has vowed has said he will keep pensioner benefits in place until 2015.
