Campaigning in the general election is resuming today after it was suspended following the terror atrocity in Manchester.

Both Labour and the Conservatives will re-start their campaigns in the shadow of the suicide attack that left 22 dead.

The Labour leader Jeremy Corbyn is expected to make a speech in which he will highlight cuts to police numbers and say it has left the country vulnerable.

He will also say UK foreign policy would change under a Labour government to one that "reduces rather than increases the threat" to the country.

Meanwhile, the KM Group has been told that Conservative supporters and members from some Kent constituencies are being drafted in to help out in the campaign in marginal seats in Sussex, such as Eastbourne.

A Conservative source said party managers were encouraging activists to help out with the campaign in the neighbouring county where the party was facing a challenge from the Lib Dems.

“We’ve been asked to help out in Sussex seats where it is felt we are more vulnerable to the Liberal Democrats,” the source said.

It will be seen as a sign that the party is confident it will not be threatened in Kent, where it currently holds all 17 seats.

Meanwhile, Ukip launched its manifesto yesterday in which it confirmed it would introduce a "one in, one out" immigration system and set a target to reduce net migration to zero over a five-year period.
