US rapper and singer Post Malone has been forced to reschedule his two stadium shows in London because of planned Tube strikes.

The 30-year-old rap star was due to perform on Sunday 7 September and Monday 8 September at the Tottenham Hotspur Stadium, but promoters Live Nation said no event license couldn’t be provided without adequate public transport.

Instead, shows will take place on the 20 and 21 September, with refunds available for those who cannot attend the rescheduled dates.

Members of the National Union of Rail, Maritime and Transport Workers (RMT) working on the London Underground are walking out on Sunday evening until Friday morning over pay and working conditions.

News of Post Malone’s rescheduled shows comes after Coldplay also moved the final two dates of their record-breaking 10-show run at Wembley Stadium.

The band said: “We’re very sorry for the inevitable disappointment, frustration and inconvenience that this situation causes.”

Post Malone is yet to make a statement on the rearranged dates, but his promoters said it would be “impossible to get people to the concert and home again safely” without London Underground services.

Some fans have complained about the timing of the postponement announcements for both Coldplay and Post Malone’s shows as the strikes were announced over two weeks ago.

Coldplay also rearranged their shows on 30 August.

This would have clashed with his Tottenham shows, which were postponed on Friday morning.
