Well, in 2017 with the Labour Party more than twenty points behind in the opinion polls it was being stated by many political analysts that the country did not have a strong, viable or effective opposition in Parliament.
With that "guaranteed" knowledge Theresa May called a General Election designed to wipe out the Labour Party in the House of Commons. Well, the rest is now electoral history, and May lost the Tory Party their overall majority in Parliament.
Much of that happening was put down to Jeremy Corbyn's performance on the campaign trail and he proved he still has that within him with his "they have no answers" speech in Parliament Square during the Trump visit a few weeks back.
General Election, many in the Labour movement will be shouting, " bring it on" I believe.
