Yes, I believe Lisa Smart has been formally adopted as the Libdem candidate for Hazel Grove.
Looking at Wragg's 2015 majority, however, it seems she has a mountain to climb if she is to overturn that.
General Election 2015- Conservative William Wragg 17,882
Liberal Democrat Lisa Smart 11,330
Labour Michael Taylor 7,584
UKIP Darran Palmer 5,283
Green Graham Reid 1,140
General Election 2010- Liberal Democrat Andrew Stunell 20,485
Conservative Annesley Abercorn 14,114
Labour Richard Scorer 5,234
UKIP John Whittaker 2,148
Comparing 2015 with 2010, we saw a dramatic collapse in the Libdem vote, from 20,485 in 2010 to 11,330 in 2015. Obviously there were at least two factors at work there: the national collapse in the Libdem vote after the five years of coalition, compounded by the retirement of Andrew Stunnell, who had a 'personal vote' as a well-regarded local MP.
Labour also did relatively well here last time, compared with 2010. But even if all the 2015 Labour voters felt so strongly about Brexit that they were to switch to Libdem this time (and they won't!), that would only just be enough to win the seat from Wragg. And I suspect Wragg's vote will increase, partly because many of the 5,000 UKIP voters in 2015 will return to the Tory fold now that the Tories are the Brexit party.
Prediction: across the country as a whole, the Libdems will win some seats back from the Tories in 'Remain' areas. But this is not a 'Remain' area.......
