I'm currently reading about Rosebery ... He must be a leading candidate.

Any other suggestions?

Any titillating ones will get a Supplementary.

Hello Probonopublico ~

I'm putting this in the 'comments' section, as I suspect you'd like to
hear more than one argument on your question ...

While Rosebery certainly is a candidate. Succeeding Gladstone, he
hated politics, considering it an "evil-smelling bog" and iniherited a
divided cabinet and an Obstructive House of Lords.

I suppose Rosebery's lack of enthusiasm didn't lend itself to being
one of history's better Prime Ministers, but I vote for Lord North as
the worst Prime Minister.

He seemed to misunderstand and thereby bollox up everything he
touched, from dealings with Ireland

to dealing with the American colonies (and their rebellion) -

waiting too late to consider conciliatory measures which led to the
defeat of Burgoyne's army at Saratoga in 1977.

Besides, how can you argue with the University of Wales, which
described him as Britain's worst Prime Minister in its 1997 degree
examinations?

Someone had to say it:
I'm not sure who was worst, but a couple of them were definitely the Pitts.

Why chose one, when one volunteers?

Lord Challaghan.

“I think we are all re-evaluated as time goes by and I should not be
the slightest bit surprised if there is another evaluation after I die
and people come to the conclusion that I was the worst prime minister
since Walpole”

Callaghan was in office from 1976 until 1979. He presided over the
‘Winter of discontent’.

" "It was my fault in the sense that I was the leader of the country.
…."
"I was the prime minister and we had got ourselves into a position
that was really disgraceful. It was probably a combination of weak
leadership among the trade unions and insensitivity on my part, but I
must carry the can.
"I very much regret it. Even at my present age if I were to go back
and be prime minister now I would certainly take more initiatives than
I did then." "

Wouldn't that be a nice birthday present, to be named worst Prime
Minister! -- Lord Callaghan turns 91 today.

Hi PB.  Do you mean the nastiest or the most incontinent ?
Rgs. Kemlo

Spencer Perceval.  Arthur Wellesley. Robert Peel.

Spencer Perceval for leaving office so abruptly.

Arthur Wellesley for opposeing every reform.

Robert Peel for introducing traffic police.

Hi, Simon the Magnifcent (aka Kemlo)

Did you know that Kemlo would be a good name for an Instant Coffee ...
Or something?

I am not sure how I could get a fix on those who were incontinent but
I have read that Rosebery went to Naples ... Would he have then been
in continent?

Was Spencer Percival the one who was assassinated (by mistake)?

NOW, if you were a Researcher, I could throw some supplementaries at
you!

Hi, Serenata

I must have missed the defeat of Burgoyne's army at Saratoga in 1977 ...

Which month was it?

Speaking of British PMs, my late grandmother was active in political
circles in the early 20th century.

I can proudly (and truthfully) sing "Lloyd George knew my Grandmum;
Grandmum knew Lloyd George."

Hi Bryan  
if I were a google researcher I wouldn't answer any qestion under $500
As to Sir Arthur Wellelsley remember he opposed the railways on the
grounds "it will encourage the lower orders to travel"
However he was also a shareholder in the "Great Northern"
Hi Regards Maxwell

Chamberlain, surely.

Eden a close second.

Wow Pinky!

Your Grandmum was ... well ... whatever.

Don't worry, we all have skeletons in our cupboards.

Shall I post a Supplementary on her?

LOL

Has anyone noticed the bad design of computer keyboards today.
Whenever I place my mug of coffee on the keyboard to stir in the sugar
it will invariably topple over and slop.
My previous computer had a cup holder that slid out from the front, a
well thought out design.  My current one (an iMac) does not. Any one
any suggestions on the problem? Is it worth posting this as a qestion?
