Who should I vote for in the General Election 2017?

It really depends on what issues matter to you.

All the usual talking points are being rolled out during campaigning - from skills to schools and health to homelessness.

But the elephant in the room is Europe and the Brexit negotiations.

"The country is coming together, but Westminster is not,” the Prime Minister said when she announced the election.

"Division in Westminster will risk our ability to make a success of Brexit and it will cause damaging uncertainty and instability to the country.

"So we need a General Election and we need one now, because we have at this moment a one-off chance to get this done while the European Union agrees its negotiating position and before the detailed talks begin.”

Conservatives

The Tories have revealed they will:

The manifesto - launched on May 18 - promised no one will have to sell their property in their lifetime to fund residential or home care, with the cost of care instead taken from their estate if it is worth at least £100,000 when they die.

Other manifesto promises include:

Scrapping winter fuel payments to better-off pensioners

An extra £4bn on schools in England by 2022 - partly funded by an end to free school lunches for all infant pupils in England

Scrapping the triple-lock on the state pension after 2020 and replacing it with a "double lock", rising with earnings or inflation

Mrs May has said that the Tory Party can offer Britain a “strong and stable leadership in the national interest, with me as your Prime Minister”.

Where do the parties stand on Brexit?

Conservatives

Tory Prime Minister Theresa May was against Brexit before the EU referendum but now says there can be no turning back and that "Brexit means Brexit". The reason she gave for calling a General Election was to strengthen her hand in negotiations with the EU, in which she plans to withdraw the UK from the single market and strike a new free trade deal. More Tory MPs backed Remain than Leave in last year's referendum - but they now strongly support the UK leaving - in February, only one voted against the government beginning Brexit by invoking Article 50 of the Lisbon Treaty.

Labour

The Party campaigned against Brexit in the referendum but now says the result must be honoured, provided workers' rights, access to the benefits of the single market and four other tests are met. It has also ruled out a second referendum on the final deal, but wants MPs to have a decisive say on what happens once negotiations are complete. And it would guarantee the right of EU nationals living and working in the UK to stay in the country from "day one" of a Labour government. The vast majority of Labour MPs backed Remain ahead of the referendum - but most followed party orders to allow Article 50 to be invoked in February's vote.

Lib Dems

The Liberal Democrats are strongly pro-EU, and have promised to stop what they call a "disastrous hard Brexit". They say they will fight with "every fibre of their being" to protect existing aspects of EU membership, such as the single market and the free movement of people, and want another referendum - this time on the terms of the deal struck between the UK and the EU. All of the Lib Dem MPs backed staying in the EU, and seven out of nine opposed Article 50, with two abstaining.

SNP

Leader Nicola Sturgeon has been pushing for Scotland - which voted to remain in the EU - to have a special status after Brexit, including remaining in the single market. She has called for a second independence referendum before the Brexit package has been finalised. The SNP's 54 MPs voted en masse against triggering Article 50 and are expected to maintain their vocal opposition to Brexit in the next Parliament.

The Green Party

Green Party of England and Wales joint leader Caroline Lucas has called for a second EU referendum on the Brexit deal reached with Brussels, and the Greens have promised "full opposition" to what they call "extreme Brexit".

Ukip

Leader Paul Nuttall has vowed to "hold the government's feet to the fire" on Brexit and will be hoping to take votes from Labour in areas that backed Leave. But with the formal exit process already under way, will the party's longstanding anti-EU message still have the same resonance.
