Iain Duncan Smith made more than treble the average Joe’s monthly salary for just one speech, we can reveal.

According to the MP for Chingford and Woodford Green’s latest register of financial interests, he made a grand total of £28,780 doing eight speeches.

Mr Duncan Smith claimed the extra-curricular work lasted 34 hours, leaving his average hourly rate for speeches at £846.

On October 31, last year, the senior Tory raked in £4,500 for two speeches for Target Jobs and Scottish Widows Bank.

He also made £5,000 delivering a speech to the Leicester Tigers rugby team on December 16.

But the most lucrative speech he made was to 2Plan Wealth Management Ltd, who paid him £6,280 for five hours work.

To put that into perspective, the average annual salary for his constituents in Waltham Forest is £30,900, according to Waltham Forest Council's website.

After tax, this leaves the average Joe with £2,024 in his pocket every month, meaning Mr Duncan Smith made more than treble that for half a day’s work.

On top of his speech-making, Mr Duncan Smith was paid £2,350 by The Daily Mail for three articles in January for six hours work.

The Sun paid the former work and pensions secretary £3,200 for six articles between September 2016 and March, that took 11 hours of his time.

That gives the senior Tory a grand total of £34,330 for money made between June 2016 and May 2017, in addition to his annual salary of £74,000 as MP.

In the latest statement, Mr Duncan Smith declares he is a member of two gentlemen’s clubs in London.

He accepted honorary life membership of Buck’s Club, in Mayfair, and he is a special member of the Pratt’s Club

Pratt’s is an exclusive all male dining club, in St James Street, and is owned by the Duke of Devonshire.

At Pratt’s, every member of staff is referred to as ‘George’ to avoid confusion.

Notable members in its history include Harold Macmillan, the Conservative prime minister from 1957 to 1963.
