The Labour Party may have overestimated the NHS in West Cumbria as a trump card to play in the by-election that saw them lose the seat, according to one political expert.
Campaigners supporting Gillian Troughton, the Labour candidate, saw the threat to move some services from the West Cumberland Hospital in Whitehaven to the Carlisle hospital 40 miles away as a key issue .
But Dr Stuart Wilks-Heeg, head of politics at Liverpool University, says the party's strategy of focussing on the NHS didn't seem to work for them.
Quote MessageIf it hasn't worked in Copeland, it may not work nationally, in spite of this very acute sense of crisis in the NHS.

In a speech in London, Mr Corbyn said: "Labour's victory in Stoke-on-Trent Central was a decisive rejection of UKIP's politics of division and dishonesty, and I congratulate Gareth Snell on his election.
"But our message was not enough to win through in Copeland, and I congratulate Gillian Troughton on the campaign that she fought.
"In both campaigns, Labour listened to thousands of voters on the doorstep. Both constituencies - like so many in Britain - have been let down by the political establishment.
"To win power to rebuild and transform Britain, Labour will go further to reconnect with our supporters and voters in general."

The former MP Jamie Reed, whose resignation prompted the Copeland by-election, says it was Labour voters staying at home, not changing their allegiance to the Conservatives, that lost the seat.

"Celebration and disappointment", says Labour leader

"We defeated UKIP in Stoke, despite all predictions that they would prevail; the politics of hope have prevailed over the politics of hatred.
Quote MessageCopeland was obviously very disappointing. I had hoped we would have won the election there. We didn't.

MP for Carlisle, John Stevenson, told BBC Radio Cumbria he was looking forward to working with Mrs Harrison: "We have some common interests, the A595 being the obvious one, we have common interests with regard to the hospitals and the nuclear industry is vital to the whole county, so there's a lot of things where MPs can work together."

Image source, ReutersPaul Nuttall had hoped to become UKIP's second MP, joining colleague Douglas Carswell at Westminster.
Nuttall, a 39-year-old Member of the European Parliament, served as UKIP's deputy leader for six years before being elected leader last year with 62.6% of support among party members.
He was pinning his hopes on Stoke-on-Trent - which recorded one of the highest proportions of Leave votes anywhere in the UK in last summer's EU referendum.
But Nuttall's campaign was dogged by personal gaffes - culminating in a fierce backlash earlier this month over false claims he lost close friends in the Hillsborough tragedy.
The BBC's Norman Smith says the party believes Nuttall is a victim of a smear campaign:

Tory party Chairman Sir Patrick McLoughlin told Good Morning Britain: "This is an amazing result for the Conservative Party.
"By-elections come and go, this one will be remembered for many, many years to come.
"It is a truly historic by-election. What we have seen today is something that we haven't seen in British politics in the last 40 years".
Labour councillor for Meir North in Stoke-on-Trent, Ruth Rosenau, , external says despite the Labour win, the fact that their majority has been halved is worrying.
Quote MessageI think it is a concern and I think it has absolutely shown us we need to reconnect with people far more in the communities - I think that has come across in the run-up to the by-election."

From Churchill to Goldsmith

Parliamentary by-elections have produced some memorable moments in British political history.

Labour MP Jack Dromey, who ran the Stoke Central campaign, says his party is not yet "a credible alternative government", but its by-election victory for Gareth Snell is "a decisive moment".
He says there is a view that his party is "not listening" but the by-election win shows "what we have done in this community is precisely to do that".
Quote MessageAre we yet a credible alternative government? No we're not. But tonight is a decisive moment."

Professor Mick Temple, from Staffordshire University, has praised the way Labour organised their campaign in Stoke Central.
He's been with the Radio Stoke breakfast show to share his expert opinion on the by-election, won by Labour's Gareth Snell (pictured).
