NICK CLEGG pocketed a five-figure speaking fee from a billionaire whose pharmaceutical company is registered in a tax haven, the register of MPs’ interests reveals.

An updated register released yesterday shows the former deputy prime minister received £30,000 from Frederik Paulsen, who Forbes has estimated is worth £4.5 billion.

Mr Clegg received the sum for “delivering a speech and participating in a roundtable debate” during an all-expenses-paid trip to Geneva, Switzerland, according to the entry.
