Sajid Javid

The Culture Secretary is already a high flyer, having joined the Cabinet after becoming an MP for the first time in 2010.

If the Conservatives win the next election, the Conservative MP for Bromsgrove can expect to continue playing a front-line role. He's young, eloquent and is someone the party can happily send out in front of the television cameras.

If the Conservatives lose the election then things might become even more interesting.

A Tory defeat will mean the party elects a new leader and Mr Javid is the type of person a future Conservative leader might want on their team – and he's already close to one of the possible winners, Chancellor George Osborne, having been his Parliamentary private Secretary and a Treasury Minister.

Liam Byrne

Yes, Liam Byrne, the Labour MP for Birmingham Hodge Hill who was kicked out of the Shadow Cabinet by Labour leader Ed Miliband for insisting Labour had to accept some of the Government's welfare reforms.

It might be tempting to think his time in the spotlight is over, even though he's tried to make the best of his new, more junior role as the shadow universities minister.

But there's a chance Ed Miliband or (if Labour loses) a new Labour leader will see sense and bring one of their most capable MPs back to the top table.

Otherwise, Mr Byrne will keep himself busy with a new project looking for ways businesses can contribute to social justice, backed by Michael Heseltine and the Bishop of Birmingham among others.

John Hemming

Liberal Democrat MP John Hemming could be one to watch in 2015 – as long as he holds his Birmingham Yardley seat, where Labour's Jess Phillips, currently a city councillor, hopes to win.

Mr Hemming's strategy is to appeal to Conservatives in the seat, which the Tories held from 1979 to 1992, to back him in order to keep Labour out.

As an MP he's campaigned on some controversial issues such as the apparent failings of the family courts, and no doubt there will be more of that if he gets back in.

But what will be really fascinating to watch is the battle for Yardley.

Lorely Burt

The Lib Dem MP for Solihull is another one to watch, again not so much because of what she will do as an MP but because the battle for her seat is set to be so enthralling.

Solihull was once a true-blue Tory bastion, but that changed when Ms Burt took the seat in 2005.

She was helped, perhaps, by dissatisfaction with the long-serving Tory MP, as well as by a dramatic fall in the Labour vote, prompted perhaps by the invasion of Iraq.

This time around it is the Lib Dems who face problems. Some local voters on the left appear to have switched from the Lib Dems to the Greens, and Greens now constitute the official opposition on the Tory-led council.

Conservatives hope to win back the seat and have a capable candidate in the form of journalist Julian Knight.

He has campaigned as the borough's "Shadow MP", even holding advice surgeries in a local supermarket - which led to a confrontation between Ms Burt and Mr Knight in front of bemused shoppers.

Pat McFadden

The Labour MP for Wolverhampton South East was initially sidelined by Labour leader Ed Miliband, perhaps because he is seen as a "Blairite" and reportedly because he wasn't keen to accept a junior role, and so ended up with nothing.

That's changed, and he returned as Shadow Minister for Europe in October. If Labour win then Europe is going to be a hot potato.

Like the Tories, Labour have a vague and possibly impractical commitment to redrawing the rules on free movement within the EU.

He could also be in line for promotion, now that he's back in the fold. Friend and foe alike regard Mr McFadden as a capable operator.

Ian Austin

Another battle for the ages is set to break out in Mr Austin's constituency of Dudley North.

This time the fight is between Mr Austin, the Labour candidate and UKIP, which appears to regard the seat as its best hope of winning in the West Midlands.

The UKIP candidate is Bill Etheridge, already an MEP and councillor, who epitomises the party's populist appeal, campaigning against zero hours contracts and police service cuts while simultaneously attacking Labour and Tory-led governments for allowing "uncontrolled immigration".

It's an approach that defies easy categorisation as left or right wing, and which the traditional parties have found hard to counter.

However, if anybody is up to the challenge it's probably Mr Austin, who comes from the working-class, down-to-earth Labour party tradition that shakes its head at the antics of middle-class, liberal allies in north London and the universities (see Warley MP John Spellar for another example).

Mr Etheridge is fighting against plans for a combined authority involving Birmingham and the Black Country, raising fears that it will mean Dudley is taken over by power-mad Brummies.
