A woman who has to travel to Germany for brain cancer treatment says new travel rules are adding hundreds of pounds to the cost of her therapy. Natalie Paul, from Bubbenhall in Warwickshire, was diagnosed with an aggressive brain tumour in 2017. When chemotherapy failed, she started a course of treatment in Cologne but faces high costs from new regulations covering both coronavirus and Brexit. The government said it was considering medical exemptions for its Covid rules. The new regulations, introduced this week, say that travellers must take a coronavirus test before leaving the UK and again on days two and eight of quarantine on their return, but they need to pay for these tests themselves.
