Primary school pupils in England could face formal tests at the age of seven - and a pool of "elite teachers" will be recruited to work in struggling schools in coastal towns.

Education Secretary Nicky Morgan is to announce a package of measures aimed at tackling underachievement.

A target will require 90% of pupils to take core academic subjects at GCSE.

Head teachers' leaders warned a teacher shortage in some subjects made that target "immensely challenging".

Mrs Morgan says the changes will help ensure "every young person gets the best start in life".
