Statement from Caroline Lucas on today's events
Caroline Lucas, the co-leader of the Green Party, has responded to today's attack in Westminster.
"Our thoughts go out to all those affected by today's attacks and we send deep thanks to the public servants who responded so quickly, bravely, and with care to treat the injured and minimise the number of casualties. We pay tribute to the lives that were so sadly lost and in particular to the police officer who died in the line of duty - we are truly in his debt.
“The response to such a heinous attack must be to strengthen our democracy, and refuse to give in to those who would harm it.”
