article: Three key constituencies - Wavertree, Southport and Wirral West - have been chosen and you'll get the chance to grill the candidates hoping to enjoy the privilege of representing you at Westminster for the next five years. Roger Phillips will be hosting the first of the hour-long debates in Wavertree - one of Liverpool's so-called safe Labour seats - from 12:00 BST. Situated to the east of the city centre, the constituency is predominantly residential. It hosts a large technology park, which has close ties to the university, and has a large student population which boosts the local economy. Voters will hope that they are not faced with a repeat of the 2010 fiasco in which the polling station on Dunbabin Road ran out of ballot papers just as the polls were about to close. Liverpool City Council say "the problems last time at a small number of polling stations were caused by a number of people turning up at the close of polls and not all of the polling stations had a full allocation of ballot papers. "We are ensuring that all stations have a full allocation and additional training has been provided for staff. Also anyone in the queue by 22:00 BST will be given the chance to vote." So who will be vying for those votes? Luciana Berger, the shadow health minister, easily held the seat for Labour five years ago with a majority of more than 7,000. She took over from Jane Kennedy - the constituency's MP since it was created in 1997 - who was elected Merseyside's Police Commissioner in 2012. At one stage it looked like former Labour Councillor Jake Morrison would stand against Ms Berger. He was only 18 when he was elected in 2011 but his relationship with the party turned sour last year when he announced his retirement at the grand old age of 22. If re-elected, Ms Berger says she would "take practical action to support people who are looking for a job, for example by holding another jobs fair to bring together employers and local people. I'll promote apprenticeships and opportunities for young people and back our fantastic small businesses". She added: "I will continue to campaign for changes to law around dangerous dogs to make our neighbourhoods safer, and I will build on my strong record of standing up for the people of Liverpool Wavertree to ensure their concerns are heard where it matters and that real change is delivered for our community." The Liberal Democrats targeted this seat in 2010 without success. Their hopes this time around rest with 20-year-old student Leo Evans. He's pledging to protect green spaces like Calderstones Park, increase the NHS budget by £8bn a year with much emphasis on mental health, work to ensure Liverpool benefits from any devolved power - especially ensuring connection to HS2 and HS3 - and continue "the biggest expansion of apprenticeships since the 1950s". James Pearson is the Conservative's candidate. The former Trafford councillor unsuccessfully stood for the Church ward in last year's Liverpool City Council elections, and this
