Texas governor signs largest US school voucher law in win for conservatives

State becomes 16th to allow public funds to be used for private schools, which opponents say will benefit mostly wealthier children

The Texas governor Greg Abbott on Saturday signed a law making more than 5 million students eligible to use state funds for private schools, a watershed moment in the conservative campaign to remake public education in the US.

Texas is allocating $1bn for the first two years of the program to offer parents vouchers to pay for school. It is the 16th state to make all students eligible to receive public funds for private education.
