As already mentioned above, flying due east from L'pool R/W 09 will very quickly put you in direct conflict with Manchester's traffic. You don't say what A/C type is involved (ie single engine performance), but if straight ahead is initially essential to achieve minimum control speed, then obviously you have no choice. Whilst appreciating that this will already be a period of very high pilot workload, and that controlling the A/C is your first priority, inform ATC (PAN and TXP #7700) ASAP. Let ATC know just as soon as you are able to safely turn, specify your preferred direction of turn, if applicable, and your intentions - return/hold/divert.
